Visit the website of World Bank Open Data Look for the data on per capita GDP and exports of all countries in the database.a. For each variable, solve for the mean and standard deviation.b. Use the normal distribution to estimate the percentage of countries with per capita GDP that is 25 percent above the mean.c. Use the normal distribution to estimate the percentage of countries with exports that are 30 percent lower than the mean.d. Rerun the procedure with the chosen variable,a. For each variable, solve for the mean and standard deviation.b. Use the normal distribution to estimate the percentage of countries with per capita GDP that is 25 percent above the mean.c. Use the normal distribution to estimate the percentage of countries with exports that are 30 percent lower than the mean.d. Rerun the procedure with the chosen variable,
