An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 110110 engines and the mean pressure was 4.64.6 pounds/square inch (psi). Assume the population standard deviation is 0.80.8. The engineer designed the valve such that it would produce a mean pressure of 4.54.5 psi. It is believed that the valve does not perform to the specifications. A level of significance of 0.020.02 will be used. Find the value of the test statistic. Round your answer to two decimal places.
