Using the p-value approach, evaluate a left-tailed hypothesis test performed at the 1% significance level with z = -2.16. Give the p-value (report to the fourth decimal), the conclusion of the test, and explain your answer.

You work for Let’s Potato Chip Co., and have been assigned to determine if the machine that fills the chip bags is working properly. Each bag is advertised to have 10.5 oz. of chips. You take 35 bags of Let’s Chips, and weigh the chips inside. You find a sample mean of 10.274 oz. and a standard deviation of 0.687 oz. Determine the critical value needed to test this hypothesis at the 5% significance level.

A forester at a logging company believes that the logging crews working under her are not loading the log trucks with the proper amount of timber when cutting. A fully loaded log truck weighs approximately 40 tons. After weighing 47 log trucks, the forester finds an average weight of 43.9 tons with a standard deviation of 4.1 tons. Find the lower boundary for the 99% confidence interval. Round your answer to the third decimal place.
