Suppose You Regress the Number of Medals Won by Countries

Figure:
Suppose you regress the number of medals won by countries in the 1996,2000,2004,and 2008 Olympics on GDP Per Capita (Thousands) ,Population (Millions) ,and Olympic Year and that you get the results in Figure 6.1.

-Based on the estimates in Figure 6.1,you should conclude that a 1 million increase in population is estimated to be associated with

A) a statistically significant .042 increase in population.
B) a statistically significant .042 increase in the total number of medals won,holding all other independent variables constant.
C) a statistically insignificant .042 increase in the total number of medals won.
D) a statistically insignificant .042 increase in the total number of medals won,holding all other independent variables constant.
