Introduction
Purpose of this Project,to find out the releationship between population and the square of countries is tried to be understood.
This Project includes 129 observations and 30 samples.We tested with 95% cofidence interval
Step 1:State null and alternate hypotheses
Step 2:Select a level of significance
Step 3:Identify the test statistic
Step 4:Formulate a decision rule
Step 5:Take a sample,arrive at a decision
Step 1 Hypothesis Test:
Ho:The average population of countries is equal or less than 39.786.098
H1:The average population of countries is more than 39.786.098
Step 2The significance level is 0.05
Step 3Because the sample is 30,z distribution has been used
Step 4Reject Ho if z>-1.96 or z<-1.96 or if p<0.05
Step 5z<-1.65 Ho is rejected.We can conclude the average population of countries is more than 39.786.098

...MAT114 (STATISTICS) Project 2 Report Alejandra Ferrer April 15, 2014 Introduction: During an election year, there will be many polls to investigate how the 2 parties will do. The purpose of this current research was to examine how the different genders (Male and Female) and the different political parties (Democrats and Republicans) feel about how our President and Congress are handling our economy and our foreign policy. This might provide insight as to how the election may go in November of 2014. Method: To investigate these research questions and hypotheses, an online survey was created using “Survey Monkey” .A convenient sample of 30 people were asked to complete the survey online (See Appendix A for the survey).

...Data Analysis Project 1. The population being sampled is Facebook users. 2. My sample was selected by blasting my survey questions to a random bunch of my “friends” on Facebook through a private message. I randomly selected 50 people in hope to get at least 25 responses. 3. Question #1: If Facebook decides to impose a monthly charge for its use, would you pay to continue using it? Please respond YES or No. Question #2: On average, how many minutes a day do you spend on Facebook? 4. A. Nominal Data Analysis-Frequency Table Response | Frequency | Relative Frequency | YES | 9 | .36 | NO | 16 | .64 | B. Qualitative Data Analysis-Summary Statistics Measure of Center: Mean = 51.12 minutes Median= 43 minutes Mode = 45 minutes Measure of Spread: Range = 116 Interquartile range = 55 Average deviation from mean = 31.30 5. Graphic Display of Results: Conclusion: Based on the data, on average, people spend about 50 minutes per day on Facebook, give or take 30 minutes. The usage data shows spikes at low usage (0-30 minutes) and moderate usage (61-90). Furthermore, the data tells us that even though the population enjoys Facebook, most would not be willing to pay a monthly charge to continue using it. While this seems like this data may be reflective of the whole Facebook users population, because I only sampled friends, this data may not be an accurate reflection of the whole population. There is a whole younger and older population...

...Course Project Part A Math 533 Keller Graduate School of Management Sept. 13, 2013 The purpose of this report is to provide feedback to AJ Davis Department Store so that they will have a better understanding of the makeup of their customer. This report will utilize three of the five customer variables that were determined by AJ Davis. The variables that were used for this study were: Income, location, credit balance, family size, and years at current household. Using these variables I will show how there may or may not be correlations between some variables and not others. Also, numerical descriptions will be used to show mean income, minimum and maximum credit balances, and family size just to give a few examples. Now that we have established a basis for this report let’s look at the analysis of the data. The first information we are going to discuss is customer income. Here is a statistical description of the income of all 50 of the customers that were sampled for this report. Descriptive Statistics: INCOME (\$1000) Variable N Mean StDev Minimum Q1 Median Q3 INCOME(\$1000) 50 43.48 14.55 21.00 30.00 42.00 55.00 Variable Maximum INCOME(\$1000) 67.00 The information above shows that the average income of the customers at AJ Davis is \$43,480 per year given the 50 customers who were sampled. It also shows us that 25% of the customers that were sampled have an income of #30,000 or less and 75% of their customers...

...Statistics Project Anicée Ravier BCi 2015 Introduction The purpose of this study is to reveal the differences of education in the world. The collected data shows the education situation of the countries over the years from 2000 to 2013. The research conducted was based on several websites’ comparison due to the fact that most of these databases are incomplete. The report examines 11 countries from each group based on random selection, but each part of the globe. The main question to be answered is whether there is a correlation between education, living standards (education, health…) and the type of country. How has the level of education changed the world in recent years? Today, education is still inaccessible right for millions of children worldwide. Over-age children attend 72 million primary school do not attend school and more than 759 million adults are illiterate and do not have the knowledge to improve their lives and those of their children. 1 Analyse of the data Enrolment rate in primary school in 2006 and 2013 (percentage) 2006 2013 Brazil 95 95 Canada 100 100 Côte d'Ivoire 62 62 France 99 99 Germany 96 100 Guinea 51 76 Hungary 89 97 India 84 99 Niger 40 64 South Africa 87 90 United States 92 93 Total n= 11 11 Average 81.36 88.64 Median 89 95 MAX 100 100 MIN 40 62 Range 60 38 We can...

We timed customers at 6 different restaurants: From the time they ordered their food till it was delivered. We also took note of the appearance of the restaurant, employee attitude and over-all cleanliness. Red Lobster and Olive Garden were chosen because of their similar styles of service, casual dining restaurants. Logan’s and Ruth Chris were chosen because they’re both steak-houses. Foosackly’s and Five Guys were chosen because of similar service styles, grab and go. Devon recorded the food service response times on Saturday March 24, 2012.

...Table of Contents: Introduction A. Analysis of Individual Variables 1 – Sales 2 – Calls 3 – Type B. Analysis of Selected Variable Pairs 1 – Sales vs. Calls 2 – Sales vs. Type 3 – Calls vs. Type C. Conclusion Introduction In collecting this data, we are determining the number of sales the employees have closed and correlating that information to the amount of calls the employee makes during the week and type of training that each employee has received. The goal is to determine whether or not the type of training (or the lack thereof) and the amount of calls made affect the amount of sales each employee closes during the week. The inference is that the number of sales that are closed during the week are larger for those who have completed some type of training. Analysis of Individual Variables 1. Sales Mean – 42.467 Median – 42 Mode – 43,44 Range – 20 Standard Deviation – 4.259 Variance – 18.139 Once the data is organized it is clear to see the number of sales each week falls between 32 sales/wk to 52 sales/wk. The average weekly sales come to 42.467 with a majority of employees closing 42 sales or more per week. There is a difference of 20 sales from the employee with the least amount of closed sales to the employee with the most sales closed during the week. 2. Calls Mean – 162.59 Median – 161.50 Mode – 149 Range – 77 Standard Deviation – 18.46 Variance – 340.81 The number...

...PAPER OR THE PROJECT IN ANY WAY, SHAPE OR FORM. (i) Strengthening statistical capacity in support of progress toward the internationally agreed development goals in the Southern African Development Community region (ii) Implementing entities and U Secretariat partners: DESA jointly with ECA (iii) Background Statistics are an important tool in the development-policymaking processes of countries and regional organizations. They are needed for assessing the current development situation, setting objectives and targets for the future and measuring progress and development. However, a substantial gap still exists between the demand for information and the ability of most countries in the Southern African Development Community (SADC) region to routinely provide it. The SADC Regional Indicative Strategic Development Plan recognizes statistics as one of the cross-sectoral areas that need to be strengthened to foster regional cooperation and integration over the next 15 years. This project is therefore designed to improve the availability and reliability of basic data required for development planning in the SADC region, with special emphasis on data requirements for the internationally agreed development goals and the Millennium Development Goals. The project is aimed at facilitating subsequent networking among subregions through interactive sharing and management of knowledge. Furthermore, the project will strengthen links between producers and users of statistics. The project...
