$\text { Figure } 6.1$
-Based on the estimates in Figure 6.1,you should conclude that,holding all other independent variables constant,a $1,000 increase in GDP Per Capita is estimated to

• A)increase Total Medals Won by a statistically significant 0.2865 because 0 is not included in the 95% confidence interval.
• B)increase Total Medals Won by a statistically insignificant 0.2865 because 0 is included in the 95% confidence interval.
• C)increase Total Medals Won by a statistically insignificant 0.2865 because 0.2865 is included in the 95% confidence interval.
• D)increase Total Medals Won by a statistically significant 0.2865 because 0.2865 is included in the 95% confidence interval.
