(Roundyour answer to the nearest 0.1 mph.)mph Major League Baseball now records information about every pitch thrown in every game ofseason. Statistician Jim Albert compiled data about every pitch thrown by 20 starting pitchers duringthe 2009 MLB season. The data set included the type of pitch thrown (curveball, changeup, slider,etc.) as well as the speed of the ball-as it left the pitcher's hand. A histogram of speeds for all 30,740four-seam fastballs thrown by these pitchers during the 2009 season is shown below, from whichwe can see that the speeds of these fastballs follow a Normal model with mean u = 92.12 mph and astandard deviation of o = 2.43 mph.every859095100speed (mph)counts
