Question
The accompanying table lists the ages of acting award winners matched by the years in which the awards were won. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value of r. Determine
whether there is sufficient evidence to support a claim of linear correlation between the two variables. Should we expect that there would be a correlation? Use a significance level of α = 0.05.

Should we expect that there would be a correlation?
O A. Yes, because Best Actors and Best Actresses typically appear in the same movies, so we should expect the ages to be correlated.
B. No, because Best Actors and Best Actresses typically appear in different movies, so we should not expect the ages to be correlated.
C. Yes, because Best Actors and Best Actresses are typically the same age.
D. No, because Best Actors and Best Actresses are not typically the same age.
