Scatter Plots, Correlation, and Regression Lines · Example 7

The data in “MLB2019Off” gives offensive team stats for the 2019 Major League Baseball season. Use that dataset to answer the following questions:

(a) What is the equation of the regression line for runs (R) vs. hits (H)?
(b) How many runs would we expect a team to score if the team got 1500 hits in a season?
(c) Did the Kansas City Royals (KCR) overperform or underperform in terms of runs scored, based on their hit total? By how much?
(d) Write a sentence to interpret the slope of the regression line.
