Chest size might be a good predictor of body fat. Here's a scatter plot of %Body Fat vs. Chest Size.
a) Is the slope of %Body Fat on Chest Size statistically distinguishable from 0? (Perform a hypothesis test.)
b) What does the answer in part a mean about the relationship between %Body Fat and Chest Size?
We saw before that the slopes of both Waist size and Height are statistically significant when entered into a multiple regression equation. What happens if we add Chest Size to that regression? Here is the output from a regression on all three variables:
