The purpose of this project is to describe a random sample of 30 countries and infer to all of the countries in the world some characteristics. The following variables will be considered. Economy
- GDP per capita in dollars (PPP)
- Unemployment as a percent
- Gini index
People and Society
- Female literacy rate as a percent (will be missing from first world countries, use 99)
- GDP spent on education as a percent
- Infant mortality rate as total deaths per 1000 live births
- Predominant religion as one name e.g., Protestant Christianity for the United States
The project will be submitted as an Excel workbook for data and parts 1-4 and a Word or pdf file for part 5. Put the data on Sheet 1 and 1a on Sheet 2, 1b on Sheet 3, , 2 on Sheet 7 , 3 on Sheet 8, 4a on Sheet 9, 4b,c,&d on Sheet 10,4e on Sheet 11.
1. For the countries in your sample, use Excel to construct the following graphs
- GDP per capita histogram (4 points) Sheet 2
- Gini index histogram (4 points) Sheet 3
- Predominant religion pie chart (max of 9 slices) (4 points) Sheet 4
- GDP spent on education as a percent (Y) vs. GDP per capita in dollars (X) scatterplot (4 points) Sheet 5
- Infant mortality (Y) vs. Female literacy (X) scatterplot (4 points) Sheet 6
- Construct a 95% confidence interval for the worlds mean GDP per capita and mean GDP spent on education as a percent. (10 points each) Sheet 7
- Do your data support the hypothesis that more than half of the countries in the world are predominately Christian at the .05 significance level? At the .10 level? (20 points) Sheet 8
- Regression and Correlation analysis
- Determine the sample regression line relating infant mortality to female literacy and plot it on a new scattergram. (4 points) Sheet 9
- Compute the correlation coefficient and coefficient of determination. (4 points) Sheet 10
- Test the hypothesis that b1 = 0. (4 points) Sheet 10
- Compute a 90% confidence interval estimate for b1. (4 points) Sheet 10
- With 90% confidence, estimate an average for all countries and predict for an individual country the infant mortality rate when female literacy rate is .75. (4 points) Sheet 11
- Interpret in detail the specific results of the above analysis (parts 1, 2, 3, and 4) in a managerial summary of no more than one page using non-technical language, meaningful to a person who doesnt know statistics. (20 points)
Bonus: Appearance: table of contents, paging, clarity, color, illustrations (10 points)
