Esp A professional golfer is shopping for a new brand of golf ball. He likes most of the features of one particular brand, but he wants to make sure that the brand has a desirable spin rate (the rate at which the ball spins on its axis after being struck by a golf club). To test the spin rate of this new brand of ball, the golfer hits the brand of ball on 100 five-iron shots, and a computer measures the spin rate for each shot. The computer then produces the following histogram summarizing the 100 spin rates: Frequency 25- 24 24 21 20- 15- 11 11 10- 5- 5000 6000 6500 Spin rate (in revolutions per minute) 5500 7000 7500 8000 Based on the histogram, find the proportion of spin rates in the sample that are at least 5500 revolutions per minute. Write your answer as a decimal, and do not round your answer.
