The meаn length оf а cаndy bar is 43 millimeters. There is cоncern that the settings оf the machine cutting the bars have changed. Test the claim at the 0.02 level of significance that there has been no change in the mean length. The alternate hypothesis is that there has been a change. Twelve bars (n = 12) were selected at random and their lengths in millimeters recorded. The lengths (in millimeters) are 42, 39, 42, 45, 43, 40, 39, 41, 40, 42, 43, and 42. The mean of the sample is 41.5 and the standard deviation is 1.784. If the computed t = −2.913, has there been a statistically significant change in the mean length of the bars?
