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

2. A rivet is to be inserted into a hole. If the standard deviation of hole diameter exceeds 0.02 mm, there is an unacceptably high probability that the rivet will not fit. A random sample of n = 15 parts is selected, and the hole diameter is measured. The sample standard deviation of the hole diameter measurements is s = 0.016mm. At α = 0.05 conduct a hypothesis test to investigate to indicate that the standard deviation of hole diameter...
