A National Manufacturer of Ball Bearings Is Experimenting with Two

question 13

Multiple Choice

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 error from the industry standard is measured in millimeters. The results are presented next. 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. This example is what type of test?

• A) A one-sample test of means
• B) A two-sample test of means
• C) A paired t-test
• D) A test of proportions
