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?

Interstate Speeds It has been reported that the standard deviation of the speeds of drivers on Interstate 75 near Findlay, Ohio, is 8 miles per hour for all vehicles. A driver feels from experience that this is very low. A survey is conducted, and for 29 drivers the standard deviation is 9.1 miles per hour. At =α0.05, is the driver correct? Assume the variable is normally distributed. (a)State the hypotheses and identify the claim with the correct hypothesis.
1) Hypothesis Testing for Population Mean: Population Variance Known a) A restaurant claims that there is an average of 20g of sugar in each slice of their cheesecake. A testing agency purchases 28 slices and finds an average of 22g of sugar per slice. It is known that the sugar content is normally distributed with σ = 5g. Does the sample seem to indicate that the average sugar content in this restaurant's cheesecake is not 20g? Let α = 0.05.
