An engineer has 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 6.6 pounds/square inch. The valve was tested on 6 engines and the mean pressure was 6.7 pounds/square inch with a standard deviation of 0.7 Is there evidence at the 0.1 level that the valve does not perform to the specifications? Assume the population distribution is approximately normal. Step 4 of 5 : Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
