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 4.9 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 140 engines and the mean pressure was 5.0 pounds/square inch. Assume the standard deviation is known to be 0.9. A level of significance of 0.1 will be used. Make a decision to reject or fail to reject the null hypothesis.
