The purpose of this project...

The purpose of this project is to infer from a random sample of countries some characteristics of all countries in the world. Create an Excel file.

1. For the countries in your sample, use Excel to construct the following graphs

a. GDP per capita – histogram

b. Infant mortality (Y) vs. Female literacy (X) – scattergram

2. Construct a 95% confidence interval estimate of the mean GDP per capita, μ, for all countries in the world.

3. Do your data support the hypothesis that the proportion of countries in the world with unemployment under 10%, P, is less than one-half at the .10 significance level?

4. Determine the sample regression line relating infant mortality to female literacy and plot it on a new scattergram. Test the hypothesis that β1 = 0. Compute a 95% confidence interval estimate for β1. Compute a correlation coefficient and coefficient of determination.

5. Interpret the results of the above analysis in a report of no more than one page using non-technical language. This interpretation should be meaningful to a person who has never had a statistics course.
