Two companies manufacture a rubber material intended for use in an automotive application. The part will be subjected to abrasive wear in the field application, so we decide to compare the material produced by each company in a test. A random sample of 35 samples of material from each company are tested in an abrasion test and the amount of wear after 1000 cycles is observed. For company 1, the sample mean of wear is X1 = 22 mg/ 1000 cycles and sample standard deviation of wear is S1 = 3 mg/ 1000 cycles, while for company 2, we obtain X, = 25 mg/ 1000 cycles and sample standard deviation of wear is S, = 9 mg/ 1000 %3D cycles. Test the hypothesis that the two companies produce material with different mean wear. Use a = 0.01. (1) Critical Region: or z > (Give your answer to 3 decimal places.)

A local DMV (location of your choice) wanted to assess the number of mistakes that were made by its operators (aka clerks). One hundred samples were gathered from each of 20 operators (note: n = 100 for calculation of σp but you will need 100 * 20 to calculate p-bar). The results are shown in the table below. The DMV wants to set control limits to include 95% of the random variation.
