\"image<\/div><\/div><\/div> Correct An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 210 engines and the mean pressure was 5,0 pounds\/square inch (psi), Assume the population standard deviation is 0.9. The engineer designed the valve such that it would produce a mean pressure of 4.9 psi. It is believed that the valve does not perform to the specifications, A level of significance of 0.02 will be used. Find the value of the test statistic. Round your answer to two decimal places.
