A professional golfer is shopping for a new brand of golf ball. She likes most of the features of one particular brand, but she 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 shots, and a computer measures the spin rate for each shot. The oomputer then produces the following histogram summarizing the 100 spin rates. Relative frequency 0.3 0.24 _. 0'25 0.22 0.2 0.11 0.1 .. . 0.1 0.08 r -- ' la 5000 5500 6000 6500 7000 7500 8000 Spin rate (in revofut'rons per minute) Based on the histogram, nd the proportion of spin rates in the samw that are at least 7500 revolutions per minute. Write your answer as a decimal, and do not round your
