...us/product/bis-155-week-7-ilab/ Contact us at: SUPPORT@WISEAMERICAN.US Week 7 iLab BIS 155 Scenario/Summary Hopefully you will find this week’s iLab activity fun and useful. We’ll be exploring the world of statistics from a business perspective this week, allowing you to practice your skills with descriptive statistics, formatting, graphs, and regression analysis. As discussed in the lesson, the value of statistics lies in the ability to analyze data more effectively for the purpose of improving decision making. You might have heard the expression that “statistics never lie, and only liars use statistics”. There is an obvious truth in this statement, in that, depending on the questions being asked and the data collected, the statistics can skew reality. For example, it is true that as ice cream sales increase, accidents at swimming pools increase. Does this mean that the more ice cream that is sold, the more accidents it causes (correlation/causation)? Of course not, but the data, if not interpreted correctly, could lead to false conclusions. It just so happens that both are correlated to a rise in temperature in the summertime. The hotter it is outside, the more kids flock to swimming pools, leading to more accidents, and the more ice cream is sold. So you see, although statistics are vital in the world of decision making, you have to be wise, and ask the right questions.

...study review. Analyzing the descriptive statistics helps our team breakdown the basic features of quantitative data results from the survey. However, we do not want to risk the chance of distorting our original findings, but use these statistics to analyze the comparisons of answers from employees and departments. Utilizing the central tendency which are three measures: mean, mode, and median allows us to give senior management raw data to make better decisions with. Measures of Variability findings enables us to differentiate results from BIMS surveys which differs from their mean. Our overall recommendation and analysis will be given to senior management within this paper off the current raw data. Data Collected The type of data collected in the survey conducted was quantitative as the data collected in the surveys was expressed numerically. Some of the questions were qualitative however the responses given were provided based on a numerical response. The survey had employees’ answer the question provided based on a scale 1-5, one being very negative and five being very positive. The data collected was later coded and entered into a spreadsheet by Debbie’s office support staff however; some errors existed when keying in the wrong number for the response provided and inputting zeros when the option was not available to employees, zero indicated no response was provided. Level of Measurement This survey had two sections. The first section consisted of ten variables and four...

...workforce. The first survey results failed to reveal the problems within the workforce that BIMS needs to identify and solve the issues of low morale and high turnover with the organization. This report will analyze B survey, explain the results, and provide a recommendation for the problems uncovered the analysis of BIMS workforce. This report will define statistics and introduce how to analyze and interpret data. The case study used in this report is BIMS LLC, a cleaning, and housekeeping company. This report will present how number data and graphing is used in analyzing data. This report will present an explicit hypothesis. This report will conclude with precise resolutions that will assist the company to move onward to a superior company. Statistics is the science of accumulating and assessing numerical evidence in an enormous measure, especially for the determination of reducing proportions in total from those in a descriptive sample. There are two types of statistics, and one is called descriptive and the other inferential. Descriptive statistics is a technique used to organize, summarize, display facts in a useful manner. Inferential statistics is the procedure used to measure assets of a population on the basis of a model. The description the part that statistics plays in the decision-making process in business is critical. In business, the proposal has statistics to display either how the business will grow or how it will not sustain its profit. Statistics is desired...

...The steps in testing a research hypothesis There are a total of five steps that are used in testing a hypothesis and they are: “(1) Making assumptions, (2) Stating the research and null hypotheses and selecting (setting) alpha, (3) Selecting the sampling distribution and specifying the test statistic, (4) Computing the test statistic, and (5) Making a decision and interpreting the results.” (Boston University Metropolitan College, n.d., Para. 1). When beginning the process of creating a hypothesis to test, the first thing that must be done is to make assumptions about the type of sampling method that would be used, the level of measurement for the variable, including the sample size. The second step is then to state the research and null hypotheses and selecting the alpha. “We always state research hypotheses in terms of population parameters because we want to use sample statistics to estimate population parameters.” (Boston University Metropolitan College, n.d., Para. 5). After the research has been stated, then the next step is to complete the null hypothesis, which will contradict the research hypothesis. The third step in testing a hypothesis is to select the sampling distribution and to specify the test statistic. The fourth step is to compute the test statistic following the specified formula to be able to test the statistic. The fifth and final step is to make a decision and to interpret the results. This simply means that we are looking over the results and deciding...

... Today, the five most popular web browsers that users have are: Internet Explorer, Fire Fox, Chrome, Safari, and Opera. From a marketing standpoint, it is important to have the capability to produce a product in the most common environments for that product, after all, one would not build a restaurant in an area with ten people in 50 square miles. As for a web browser, these five are it. These popular browsers have different features that make them stand out from one another. Here are some basic features and explanations for the top five popularity: * Internet Explorer used to be the most popular choice for years and is seen most commonly on Widows platforms. It is considered for its speed, tab isolation, as well as its clean interface. * Firefox is todays second pick according to W2Schools statistics. Today it is popular for its vast cross platform capabilities and its add-ons and extensions. * The most popular web browser today is Google’s Chrome. According to Helen (2012), Chrome was the first browser to introduce tab isolation and one box for both addresses and searches. Chrome is also popular for many of developer’s resources. * Safari was introduced by Apple and is used most commonly on its Mac Operating Systems. An advantage to using this browser is if one has more than one apple product, ICloud will sync all open tabs, bookmarks, reading list, etc. * According to W2Schools statistics, the least popular web browser of the top five is Opera.

Philosophical and health issues are prompting an increasing number of Taiwanese to switch to a vegetarian lifestyle. A study by Lu et al., published in the Journal of Nutrition (Vol. 130, pp. 1591-1596), compared the daily intake of nutrients by vegetarians and omnivores living in Taiwan. Among the nutrients considered was protein. Too little protein stunts growth and interferes with all bodily functions; too much protein puts a strain on the kidneys, can cause diarrhea and dehydration, and can leach calcium from bones and teeth. Independent random samples of 51 female vegetarians and 53 female omnivores yielded the data, in grams, on daily protein intake presented in the Chapter 10 data sets, problem #10.51. Do the data provide sufficient evidence to conclude that the mean daily protein intakes of female vegetarians and female omnivores differ? Perform the required hypothesis test at the 1% significance level. a. Determine and state the type of test that should be performed to answer the...

...data. (See attached spread sheet). To calculate the mean, median and standard deviation for the ounces in the bottles I first imported the data in excel. After importing the data I use the Data analysis function where I choose descriptive statistics. Once choosing descriptive statistics I clicked ok and input my data range. Afterward I selected summary statistics and press OK. The forwarding data was provided; the mean equaling 14.87, median equaling 14.8, standard deviation equaling 0.550. To construct a ninety-five confidence interval for the ounces in the bottles I use the following information. X equal to 14.87 which is the mean of the data from the bottles, n equal to 30, because of the amount of bottles we use, standard deviation equals zero point five five zero which was calculate with the data from the bottles. I use the formula [ ] which gave me the lower limit of 14.673 and an upper limit of 15.067. Finally I conducted a hypothesis test to verify if the claim that a bottle contains less than sixteen ounces is supported. With the claim that the bottles contains less than sixteen ounces my null hypothesis is mean greater than equal to sixteen and my alternative hypothesis is mean less than sixteen. Using the formula [ ] I calculated that the value of the test statistic is negative eleven point two five three. With the critical value at the...

...Garbutt-Taylor, Sarah Billingham, Shunta Dow QNT/351 September 15, 2014 Mark Salaaka Reflection “The hypothesis guides us on the selection of a certain design, observation and methods of researching over others. If we could test the whole populations directly, we would not need to formulate hypothesis, conduct inferential statistics and make inferences for the population based on a sample. However, it is often impossible to test the whole population, and we need to make our observations based on a sample (University of Strathclyde Humanities & Social Studies, n.d.).” “Hypothesis testing is all about populations and using a sample based in which we make inferences about the population” (University of Strathclyde Humanities & Social Studies, n.d.). The basic logic is to prove or disprove the research question. There are five steps that consist of all the decisions a researchers needs to make in order to answer any research question. Steps in Testing a Research Hypothesis 1. Stating the Research Question. “This step makes the researcher not only define what is to be tested but what variable will be used in sample data collection” ("Five Steps of Hypothesis Testing", 2014). 2. Specify the Null and Alternative Hypothesis – According to the University of North Carolina (2014), "The second step is to state the research question in terms of a null hypothesis (H0) and a alternative hypothesis (HA). The null hypothesis is the population parameter, µ = $30,000...

...Charles Dong Yd461@stern.nyu.edu 347-3073175 Analyst Report for Tesla Motors, Inc The following report will explain all the summary statistics for Tesla Motors as well as all assumptions used in the equity valuation. This report serves to offer a broad overview of the general performance of the company and an analysis of its true value. It can be divided into the following sections, profitability statistics, liquidity statistics, solvency statistics, DCF valuation, relative valuation, and technical analysis. Probability Statistics: Tesla Motors does not currently have very promising profitability statistics as the company is still young and is preparing for massive production of electric vehicles. However, as seen in the model, the condition can be hugely improved in the future even in the down side case. Currently, the company faces two challenges to improve its profitability performance, increasing revenue and reducing cost of production. The company’s net revenue have grown at a very high rate in 2012 and 2013 due to the introduction of Model S. It is reasonable to expect continuous rapid growth in the next five years as well. The company will keep growing with a decreasing growth rate as the company become mature. This will eventually bring the net revenue form the current 2 billion to a sounder 8.5 billion. This projection is reasonable because market for electric cars will become very big in the next ten years and Tesla with its advanced technology and...

...Logos would be expressed throughout this video with those statistics. The potential bias of this video would revolve around feminist. I wouldn’t consider myself I huge activist for feminism but this video really struck my attention. I feel that we as women should have equal rights and should not be looked at as just “women”. These potty mouth princesses made a point with their commercial, I don’t think they had to curse so many times to get their point across but that’s the thing, their points wouldn’t have gotten across if they hadn’t cursed. This video only became viral because what 6-year-old drop F bombs and post it nationally for the whole world to see? My first reaction was utter shock that little girls at that age would post a video like that. The language used in “Potty Mouthed Princesses” is used on purposed. This tactic was to get viewer attention and for them not to focus on the language being used by the little girls but by the message they were meaning through it. Language can be a powerful tool and by allowing the girls to use it with force and anger allowed the message to be perceived as...

...manufacturing sector declined by 0.1% in Q3 2013, as hours worked increased by 1.2%. That said, productivity in durable goods increased 1.1% and decreased 1% in nondurable goods. It was the area of competitiveness that was most interesting to me. According to a 2013 report released by Deloitte, evaluating global manufacturing competitiveness, the United States did not hold the top position. As was described in that article, of the top ten countries, five are developed nations whereas five are developing nations and yet, in five years, three developing nations will likely occupy position #2 and #3 respectively. The article points to “talent-driven innovation” as the key component to a nations competitiveness. In fact, the Deloitte article goes on to state: “Talent-driven innovation is deemed the most critical driver of a nation’s competitiveness. Catapulting into the second most important driver position is the economic, trade, financial, and tax system of a nation.” (Deloitte 2013) Current competitiveness | | Competitiveness in five years | Rank | Country | Index score (10=High 1=Low) | | Rank | Country | Index score (10=High 1=Low) | 1 | China | 10.00 | | 1 | China | 10.00 | 2 | Germany | 7.98 | | 2 | India | 8.49 | 3 | USA | 7.84 | | 3 | Brazil | 7.89 | 4 | India | 7.65 | | 4 | Germany | 7.82 | 5 | S.

...negligent and drive under the influence. Which most of the time results in car accident fatalities, and can have major effects on the family or families affected by the incident. Although you probably think it could never happen to you, experts say that everyone has a 40% chance of being in a car crash involving alcohol use sometime in their life. It is wrong, irresponsible, and wastes many lives. There is nothing positive that can come out of drunk driving. There are many consequences that can result in a person driving under the influence. For example your driving record can be greatly affected, such as your license being revoked. Or you may have to pay an excessive amount of money for fines that you are charged with, starting at about five hundred dollars to one thousand dollars, depending on how many DUI convictions you have. If arrested for drunk driving, you will have to take a chemical test to get a more accurate estimate of your Blood Alcohol Concentration. You are required by the Implied consent Law to take the chemical test. If you refuse to take this test, your driver’s license will be suspended and you will be hit with yet another DUI fine. Also as part of your DUI fines, you will have to attend DUI School. The length of time you have to attend the school depends on how high your BAC was. The higher you’re BAC, the longer you must attend the DUI School. In California, for example, you can get anywhere between twelve hours to thirty months of DUI school. Underage...
