$\text { Figure } 6.1$
-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.
