Major League Baseball batters in 2017.

Assume that the conditions for inference have been satisfied.
(a) Do these data provide convincing evidence that there is a linear relationship between RBIs and Flits for Major
League Baseball batters in 2017?


(b) Construct a 95% confidence interval for the slope of the population regression line for predicting RBIs from Hits.
