11. You have designed an automatic pitching machine that you plan to market for use by baseball players. You intend that the ball hit the target within one inch, if the machine is operating properly. You also know that the degree of variability cannot exceed .025". After you have designed your first model, you need to examine whether it satisfies the 1" criterion before you pursue further research. You have the machine make 15 tosses. You observe the following distances from the target: 1.5 5" 7 1.0 75 1.1 80 1 2 1.0 1.0 1.2 9 5 6" Do a hypothesis test on these data using the <01 level of significance. Specify the null and alternative hypotheses, the critical z required to reject or accept the null, your obtained value, and your decision to reject or accept the null. (Show all your work). What do you decide to do? Do you begin the process of marketing the machine or do you need to go back and work on it some more?
