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 4.5 pounds/square inch. The valve was tested on 200 engines and the mean pressure was 4.6 pounds/square inch. Assume the standard deviation is known to be 0.6. Is there evidence at the 0.02 level that the valve performs above the specifications? Step 1 of 5 : Enter the hypotheses: An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such thatit would produce a mean pressure of 4.5 pounds/square inch. The valve was tested on 200 engines and the mean pressure was 4.6 pounds/square inch. Assume the standard devation is known to be 0.6. is there evidence at the 0.02 level that the valve performs above the specifications? Step 2 of 5: Enter the value of the zest statistic. Round your answer to two decimai places. An engineer designed a valve that will regulate water pressure on an atitomobile engine. The engineer designed the valve such that it would produce a mean pressure of 4.5 pounds/5quare inch. The valye was tested on 200 engines and the mean pressure was 4,6 pounds/square inch. Assume the staridard deviation is known to be 0.6 is there evidence at the 0.02 level that the valve performs above the specifications? Step 3 of 5 : Specify if the test is one-tailed or two-talled. 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 4.5 pounds/square inch. The valve was tested on 200 engines and the mean pressure was 4.6 pounds/square inch. Assume the standard deviation is known to be 0.6. Is there evidence at the 0.02 level that the valve performs above the specifications? Step 4 of 5 : Enter the decision rule.
