Brief Description

JET Copies was created to solve a problem of resource scarcity, James, Ernie, and Terri all students were having challenges trying to get their copies. They were traveling to another building outside of theirs and several students were using the same copier. James thought they could make a lot of money if they purchased a copier and charged students 0.10 cents a copy. So James, Ernie, and Terri borrowed $18,000.00 dollars from their parents and went into business.

Simulation Estimate

I took the example from page 647 in our text and used it as a template to create my model. I used the discrete distribution table shown on page 679 to gather my information that stipulated repair times in days with the corresponding probability. The probability distribution was located on page 679 as well and gave a 0 to 6 week timeframe between break downs. I used the continuous probability function in excel to show the values. To compute the loss of revenue over 1 year I calculated all values then divided them by the cumulative total divided by 52 weeks for an average annual cost of $ 58,231 dollars.

Case Problem Question

Should JET buy a backup copier for $ 8000.00 dollars so they do not lose revenue when their main copier is being fixed? Yes they should purchase a backup copier because the revenue lost will significantly impact their copy business. My confidence level is very solid, in the fact that a backup copier is a wise investment given the information supplied by the simulation and the side bar information provided by the Deans office from employees that use the copier.

Limits of the Study

There was no SWOT analysis done prior to the purchase, and the JET executives how no concrete information accept for what they gathered from the Dean’s office and their own experiences concerning the copier and the intended consumer need.

...This paper will explain what statistics are. Statistics are used in so many ways, including business. This paper will thoroughly defining statistics, the types and levels of statistics, the role of statistics in a business and examples of how statistics may be used. The most common definition for statistics would be the collection of numerical data. Examples of numerical data could be the percentage of how many African-Americans passed, dropped out or failed out of high school in Vallejo, CA in 2013. Another would be how many slam dunks did LeBron James have last year or asking how many assist did LeBron James average last season; would give you numerical data. In this coarse, statistics is described as the science of collecting, organizing, presenting, analyzing, and interpreting data to assist in making more effective decisions. Statistics are usually divided into two catagories, descriptive and inferential statistics. Discriptive statistics are the methods of organizing, summarizing and presenting data in an informative way. Inferential statistics (also known as statistical inference) are the methods used to estimate a property of a population on the basis of a sample. There are two variables/attributes involved in statistics, qualitative and quantitative. Qualitative variables are when the characteristics being studied are categorical or nonnumeric. Quantitative variables are when a variable is studied and the study describes how much or how many. There are four......

...Descriptive and Inferential Statistics ________________________________________ Statistics can be broken into two basic types. The first is known as descriptive statistics. This is a set of methods to describe data that we have collected. Ex. Of 350 randomly selected people in the town of Luserna, Italy, 280 people had the last name Nicolussi. An example of descriptive statistics is the following statement : "80% of these people have the last name Nicolussi." Ex. On the last 3 Sundays, Henry D. Carsalesman sold 2, 1, and 0 new cars respectively. An example of descriptive statistics is the following statement : "Henry averaged 1 new car sold for the last 3 Sundays." These are both descriptive statements because they can actually be verified from the information provided. The second type of statistics in inferential statistics. This is a set of methods used to make a generalization, estimate, prediction or decision. Ex. Of 350 randomly selected people in the town of Luserna, Italy, 280 people had the last name Nicolussi. An example of inferential statistics is the following statement : "80% of all people living in Italy have the last name Nicolussi." We have no information about all people living in Italy, just about the 350 living in Luserna. We have taken that information and generalized it to talk about all people living in Italy. The easiest way to tell that this statement is not descriptive is by trying to verify it based upon the information provided. Ex....

...determine if the data are distributed normally. The Histogram below as well as the Descriptive Statistics (Appendix 1, Table 1b) show that the data distribution is leptokurtic (kurtosis is 2,021) and negatively skewed (skewness -,240). We can determine several outliers (Appendix 1, Table 1c, Table 1d) with extreme ratios. In cases #46 and #178 JSL is more than the highest option provided in the questionnaire. That could be a mistake in data entering or the respondent wanted to emphasise his/her satisfaction level. These cases were delisted. Cases with “0” responses are to be excluded from the further analysis as irrelevant data too. After the data revision there are 194 cases left in the dataset. Although the distribution is still negativeley skewed we may observe the distribution is closer to normal in terms of kurtosis. (Appendix 2, Picture 1a, Table 1c). We checked the significance of non normal distribution by comparing the numeric value of kurtosis with twice the Std. Error of kurtosis. Looking at the range from minus twice the Std.Error of kurtosis to plus twice the Std.Error of kurtosis, we see that the kurtosis value falls within this range. Thus the non normal distribution is considered to be insignificant. The JSL variable was also tested for the the distrubution normality depending on “Branch” and “Work Exp” variables. (Appendix, Histogram). Descriptive statistics of the subsamples shows that the skewness and kurtosis is acceptable , no outliers were......

...1. Introduction Poverty, which is measured by the household income lower than poverty line has been identified as the dependent variable in this project. It is important to know which elements are associated with poverty. The purpose of this paper is to evaluate the key determinants of American household poverty in 1980. The four possible determinants will be analyzed in this project, the average numbers of every family (FAMSIZE), URB is the percent of people live in urban, UR is the level of people have no job over 16 years and the median family income in US dollars (INCOME). Descriptive statistics, correlation and regression will be used in this project. 2.

...The article I chose suggests that Roman Catholics in the United States hope that the next pope could be younger and lead the church in a more liberal way regarding issues, such as birth control and same-sex marriage. The statistics is based on the latest New York Times/CBS News telephone poll conducted on landlines and cellphones from February 23 to 27 with 1,585 adults nationwide. Three-fourths of interviewers thought Pope Benedict should step down because he did a bad job dealing with sexual abuse. The poll suggested that many American Catholics are not confident about the church’s hierarchy since the bishops and cardinals do not understand their needs. The sample of telephone poll was randomly selected to ensure that each region of the country has almost same share of all telephone numbers, so it seems justified geographically. However, there is uncertainty in the survey because the margin of sampling error is plus or minus 4% for the 580 Catholics. An effective way to reduce the margin of error is to increase the sample size. There is also nonresponse error in the survey because some people do not answer calls from strangers, or refuse to answer the poll. In addition, due to selection bias, the opinions of those who agreed to be interviewed only reflect a certain part of the population. The article did well in analyzing from a series of data, mainly on the percentage of sample size. For example, the poll showed that 40 percent thought the pope is......

...plays a role in certain areas where the recidivism rates are increasing. Lastly we will discuss several implications that could possibly reduce these rates. Introduction: A criminal career is a sequence of offenses during a period of an individual’s life. This repetitive criminal behavior is called recidivism, and indicates the proportion that becomes involved in criminal behavior, at what age criminal behaviors begins, how long the criminal career lasts and the number of offenses typically committed during the course of the career (Farrington, 1992) Also defined as an estimate of the percentage of released prisoner who commit another offense. There are three different measures of recidivism according to the Bureau of Justice Statistics. These are rearrests, reconviction, and reincarceration. Rearrests is described as any arrest that was reported to state identification bureau after release from a correctional bureau after release from a correctional institute. Reconviction can be referred to as a conviction on at least one charge after the release date. Reincarceration refers to any return to prison or any admission to a local jail with a new offense. The Problem: Recidivism is associated with increases in crime, homelessness, and family destabilization. In many cases, high recidivism results to failure to provide useful rehabilitation for offenders. Recidivism rates in urban centers tend to be higher than In rural areas. Also some factors we must......

...hospital. Lee – 20.1 I also feel that women without health insurance have a higher rate of infant mortality due to the fact that most do not have good prenatal care. While the first 4 counties on my list have a rate ratio of 18.0 without insurance, Lee county residents are at 26.6 without insurance. When comparing ethnicities, African American women had the highest rate of infant mortality with a rate ratio of 13.31 and Hispanic women from Central or South America had the lowest rate of 4.57. The United States as a whole has a rate of 2.37 with Wisconisin as having one of the highest rates. In the US unmarried mothers of all ethnicity had one of the highest rates due to the fact that prenatal care is very expensive. World statistics show at a rate ratio of 49.4 for infant mortality. Afghanistan rates at 119.41 making it one of the highest countries for infant mortality. I feel that being the 15th least developed country in the world and most people live way outside of any town causing them not to be able to seek healthcare is the reason why their mortality rate is so high. Singapore has the lowest infant mortality rate in the world. The government there provides safety nets for citizens without insurance making it possible for most to receive healthcare. The government pays 31.9% of the citizens healthcare....
