The data in "MLB20190ff" (https://openstax.org/r/Chapter8 Data-Sets) gives offensive team stats for the 2019 Major League Baseball season. Use that dataset to answer the following questions:
1. What is the equation of the regression line for runs (R) vs. hits \((H)\) ?
2. How many runs would we expect a team to score if the team got 1500 hits in a season?
3. Did the Kansas City Royals (KCR) overperform or underperform in terms of runs scored, based on their hit total? By how much?
4. Write a sentence to interpret the slope of the regression line.
