8.8 Exercise 17

The data in “WNBA2019” gives team statistics from the 2019 WNBA season. Use that dataset to answer these questions about team wins (W) and the proportion of team field goals made (FG%, the number of shots made divided by the number of shots attempted. Even though this column is labeled using a percent sign, the values are not expressed as percentages):

1. What is the equation of the regression line for wins vs. proportion of made field goals?
2. How many wins would we expect for a team that makes 42% of its shots?
3. Did the New York Liberty overperform or underperform in terms of wins, based on the team’s proportion of made field goals?
4. Write a sentence to interpret the slope of the regression line.
