A manufacturer produces crankshafts for an automobile engine. The crankshafts wear after 100,000 miles(0.0001 inch) is of interest because it is likely to have an impact on warranty claims. A random sample ofn = 15 shafts is tested and = 2.78. It is known that o = 0.9 and that wear is normally distributed.Question 1: Parameter of interest for this testQuestion 2: Test Họ: µ = 2.5 versus Hj: µ # 2.5, a = 0.05Question 3: What is the power of the test if true u = 3.10Question 4: Sample size required to detect a true mean of 3.10 if we wanted the power to be at least 0.9? Question 1a. nz 15Question 2b.n =24v Question 3C. Fail to reject Ho.

2. Consider a study where students are measured on whether they had an internship during their time at WKU (Y/N) and whether they had a job at graduation (Y/N). If we wanted to test whether having an internship was associated with having a job at graduation (i.e., internship holders were more likely to have jobs), why would the chi-square test be inappropriate for this hypothesis? How should we analyze our data?
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?

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 43 feet. Assume the population standard deviation is 4.6 feet. The mean braking distance for Make B is 46 feet. Assume the population standard deviation is 4.5 feet. At α=0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. The critical value(s) is/are Find the standardized test statistic z for μ1−μ2.
