BUSA 3321 Project      The purpose of this project is to infer   from a random sample of countries some characteristics of all countries in   the world.       From the class web site link to the CIA   Fact Book, select a random sample (using a random number table or random   number generator) of 30 countries. For each country observe the following   variables:      Economy   a. GDP per capita   b. Unemployment   c. Inflation rate   People   d. Female literacy rate    e. Infant mortality rate   f. Predominant religion      Create an Excel file.      1.     For the   countries in your sample, use Excel to construct the following graphs (4   points each)   a. GDP per capita – histogram   b. Unemployment – relative frequency   histogram   c. Inflation – ogive    d. Predominant religion – pie chart   e. Infant mortality vs. Female literacy –   scattergram

2. Construct a 95% confidence interval   for the mean GDP per capita. (20 points)

3. Do your data support the hypothesis   that more than half of the countries in the world are predominately

4. Determine the sample regression line   relating infant mortality to female literacy and plot it on a new   scattergram. Test the hypothesis that b1 = 0. Compute a 95% confidence   interval estimate for b1. Construct a confidence interval estimate of average   infant mortality for all countries with female literacy rates of .85. Predict   with an interval an individual country’s infant mortality rate when female   literacy rate is .85. Compute a correlation coefficient and coefficient of   determination. (20 points)
