A rivet is to be inserted into a hole. A random sample of n = 15 parts is selected and the hole diameter is measured. The sample standard deviation is s = 0.007 millimeters. Is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters? Use a = 0.01. (a) Calculate the test statistic y. Round your answer to two decimal places (e.g. 98.76). i (b) Is there strong evidence to indicate that the standard deviation of hole diameter exceeds 0.01 millimeters?
