An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 180180 engines and the mean pressure was 4.64.6 lbs/square inch. Assume the standard deviation is known to be 0.90.9. If the valve was designed to produce a mean pressure of 4.84.8 lbs/square inch, is there sufficient evidence at the 0.10.1 level that the valve performs below the specifications? State the null and alternative hypotheses for the above scenario.
