An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 4.1 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 120 engines and the mean pressure was 4.3 pounds/square inch. Assume the variance is known to be 0.64. A level of significance of 0.05 will be used. Make a decision to reject or fail to reject the null hypothesis. Make a decision.
