A manufacturing company is measuring the diameter of a ball bearing by 12 inspectors, each using two different kinds of calipers to test the difference between the sample means of the two calipers used. Is there a significant difference between the means of the population of measurements from which the two samples were selected? Use = 0.01, 0.05, 0.1. What is the P-value for the test in part? Do 90%, 95%, and 99% confidence intervals on the difference in mean diameter measurements for the two types of calipers.

I know how to do this on paper but not in excel. Can you also please explain everything if possible? Thanks!
