A national manufacturer of ball bearings is experimenting with two different processes for producing precision ball bearings. It is important that the diameters be as close as possible to an industry standard. The output from each process is sampled, and the average errortrom the industry standard is measured in rnillimeters The results are presented here Process B Sa nple mean ' 3 C) Standard devist'ior . Sa nple :i:e 14 The researcher is interested in determining whetherthere is evidence thatthe two processes yield different average errors The population standard deviations are unknown but are assumed equal. Assume that Process A is the first population it we test the null hypothesis at the 1% level of significance, what is the decision'J Multiple Choice 0 Reject the null hypothesis and conclude the means are the some. 0 Fail to rejec1 the null hypothesis. O Fail to rejec1 the null hypothesis and conclude 1he means are different O Reject the null hypothesis and conclude the means are different
