Problem
Question 8 of 8 , Step 5 of 6 An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 290 engines and the mean pressure was 4.1 pounds/square inch (psi). Assume the population standard deviation is 0.6 . If the valve was designed to produce a mean pressure of 4.2 psi, is there sufficient evidence at the 0.02 level that the valve does not perform to the specifications?
