The data set included the type of pitch thrown (curyeball, changeup, slider, etc.) as well as the speed of the ball as it left the pitcher's hand. A histogram of speeds for all 30,745 four-seam fastballs thrown by these pitchers during the 2018 season is shown below, from which we can see that the speeds of these fastballs follow a Normal model with mean p = 92.39 mph and a standard deviation of o = 2.21 mph. 4003 3010 I 1000 summery Compute the zvscore of pitch with speed 92.2 mph. {Round your answer to two decimal places.) |:] Approximately what fraction of these fourseam fastballs would you expect to have speeds between 90.6 mph and 94 mph? (Express your answer as a decimal. not a percent, and round to three decimal places.) Approximately what fraction of these fourvseam fastballs would you expect to have speeds above 94 mph? (Express your answer as a decimal, not a percent, and round to three decimal places.) I; A baseball fan wishes to identify the fourvseam fastballs among the slowest 19% of all such pitches.
