An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 160 engines and the mean pressure was 6.1 pounds/square inch (psi). Assume the population standard deviation is 0.6. The engineer designed the valve such that it would produce a mean pressure of 6.0 psi. It is believed that the valve does not perform to the specifications. A level of significance of 0.05 will be used. Find the value of the test statistic. Round your answer to two decimal places.

The mean volume of a large population of vials used to be 10.9 ml. To test whether this value has decreased, a random sample of size 300 vials are measured and found to have a sample mean of 10.5 ml. We will assume that the population of vial volumes is normally distributed with standard deviation of 3.6 ml. Test whether the mean population volume has decreased at a level of significance of 1%. Show your relevant steps below. Step 1: Hypotheses: • The null hypothesis Ho is (choose one): µ = 10.9 X = 10.5 x = 10.9 u = 10.5 • For the alternative hypothesis Ha we change the equal sign in Ho to (choose one):
