An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 200 engines and the mean pressure was 4.5 pounds/square inch (psi). Assume the population standard deviation is 0.7. If the valve was designed to produce a mean pressure of 4.4 psi, is there sufficient evidence at the 0.01 level that the valve does not perform to the specifications? Step 4 of 6: Find the P-value of the test statistic. Round your answer to four decimal places.
