An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 250250 engines and the mean pressure was 5.55.5 pounds/square inch (psi). Assume the population variance is 0.490.49. The engineer designed the valve such that it would produce a mean pressure of 5.45.4 psi. It is believed that the valve does not perform to the specifications. A level of significance of 0.050.05 will be used. Find the P-value of the test statistic. Round your answer to four decimal places.
