Claim: The standard deviation of pulse rates of adult males is more than 10 bpm. For a random sample of 134 adult males, the pulse rates have a standard deviation of 11.2bpm. Find the value of the test statistic. The value of the test statistic is (Round to two decimal places as needed.)
Automobile Parts: An important manufacturing process produces cylindrical component parts for the automotive industry. It is important that the process produce parts having a mean diameter of 5.0 millimeters. The engineer involved conjectures that the population mean is 5.0 millimeters. An experiment is conducted in which 100 parts produced by the process are selected randomly and the diameter measured on each. It is known that the population standard deviation is σ = 0.1 millimeter. The experiment indicates a sample average diameter of x = 5.027 millimeters. Does this sample information appear to support or refute the engineer's conjecture?
