Patrons at a local batting cage complain that a pitching machine set to throw 80 mph is throwing too slowly. A random sample of 29 pitches from the machine yields an average speed of 79.25 mph with a standard deviation of 4.22 mph. Perform a hypothesis test to see if the average speed of this machine is less than 80 mph. Select the appropriate critical value (CV), test statistic (TS), and decision, and listH0. (Useα= 0.01.)

◦

CV = –2.4671; TS = –0.96; fail to rejectH0t: the machine throws at less than 80 mph


◦

CV = –1.3125; TS = –0.82; fail to rejectH0: the machine throws at less than 80 mph


◦

CV = –2.2671; TS = –0.18; fail to rejectH0: the machine throws at less than 80 mph


◦

CV = –2.4671; TS = –0.96; fail to rejectH0: the machine throws at 80 mph
