I man (1994) reports that for professional golfers, a regression equation relating x = putting distance (in feet) and y = success rate (in percent) based on observations of distances ranging from 5 feet to 15 feet is
Success rate = 76.5 - 3.95 (Distance)
a. What percentage of success would you expect for these professional golfers if the putting distance was 10 feet?
b. Explain what the slope of 3.95 means in terms of how success changes with distance.
