An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 150 engines and the mean pressure was 5.2 Ibs/square inch, Assume the standard deviation is known to be 0.9, If the valve was designed to produce a mean pressure of 5.3 Ibs/square inch, is there sufficient evidence at the 0.02 level that the valve performs below the specifications? State the null and alternative hypotheses for the above scenario
