A carpet company advertises that it will deliver your carpet within 15 days of purchase. A sample of (n) 49 past customers is taken. The average delivery time in the sample was () 16.2 days. Assume the population standard deviation is known to be (a) 5.6 days. Note that the significance level is α=0.05. What are the z-score and the p-value for this sample?

A lathe is set to cut bars of steel into lengths of 6 centimeters. The lathe is considered to be in perfect adjustment if the average length of the bars it cuts is 6 centimeters. A sample of 121 bars is selected randomly and measured. It is determined that the average length of the bars in the sample is 6.08 centimeters with a standard deviation of 0.44 centimeters. Compute the p-value for testing whether the population mean is larger than 6 centimeters. NOTE: WRITE YOUR ANSWER WITH 4 DECIMAL DIGITS. DO NOT ROUND UP OR DOWN.
