Question: We have the Test scores, Happiness index, Fertility rates, Urbanization rates, and GDP of the following 4 countries: Albania, Argentina, Australia, and Austria. Answer all questions, explain all steps clearly, no assumptions.

Albania: Test score = 405; Happiness index = 4.586; Fertility = 1.64; Urbanization rate = 62.1; GDP = 13496

Argentina: Test score = 402; Happiness index = 6.388; Fertility = 2.4; Urbanization rate = 92.1; GDP = 23291

Australia: Test score = 503; Happiness index =7.272; Fertility = 1.95; Urbanization rate = 86.2 GDP = 50193

Austria: Test score = 484; Happiness index =7.139; Fertility = 1.4; Urbanization rate = 58.7; GDP = 56960

Use R-Studio to rerun the unrestricted regression in (j) on ahomoskedasticity-only basis. (Notice that GDP is now statistically significant at the 5% level. Run the linear restriction from part (j) on a homoskedasticity-onlybasis. Show all the code used to run the regression, and all the result of the regression, and your joint hypothesis test. How does the p-value of this test compare tothe p-value in part (j)?Is the statistical inference -whether or not you reject the null hypothesis-different at the 5% significance level between the two cases?
