2.12 Let y = expenditure ($) on food away from home per household member per month in the past quarter and x=1 if the household includes a member with an advanced degree, a Master’s, or Ph.D./Professional degree, and x = 0 otherwise. 2.13 Using 2011 data on 141 U.S. public research universities, we examine the relationship between academic cost per student, ACA (real total academic cost per student in thousands of dollars) and full-time enrollment FTESTU (in thousands of students). 3.2 There were 64 countries in 1992 that competed in the Olympics and won at least one medal. Let MEDALS be the total number of medals won, and let GDPB be GDP (billions of 1995 dollars). A linear regression model explaining the number of medals won is MEDALS = β1 + β2GDPB + e. The estimated relationship is given in equation (XR3.1) in Exercise 3.1. What happens to the distribution of the test statistic in part (a) if the alte...
