17) A national manufacturer of ball bearings is experimenting with two different perinte precision ball bearings. It is important that the diameters be as close as possible to The output from each process is sampled, and the average crror from the industry standard meters. The results are presented here Process 01 The researcher is interested in determining whether there is evidence that the two processes yield different average errors. The population standard deviations are unknown but are assumed equal. If we test the null hypothesis at the 19. level of significance, what is the decision? Reject the null hypothesis and conclude the means are different. Reject the mall hypothesis and conclude the means are the same Fail to reject the null hypothesis Fail to Ticct the nully the 17) A national manufacturer of ball bearings is experimenting with two different perinte precision ball bearings.
