At a tennis tournament a statistician keeps track of every serve. The statistician reported the the mean serve speed of a particular player was 97 miles per hour (mph) and the standard deviation of the serve speeds was 11 mph. Assume that the statistician also gave us the information that the distribuation of the serve speeds was bell shaped. What percentage of the players serves are expected to be between 75mph and 130mph? a) there are TWO "k" values in this problem. _____ (blank) and ____ (blank). Remember that "k" is the number of standard deviations from the mean. b) the percentage of the players served betweeen 75 and 130 is ___ (blank)
