Question 6 of 10, Step 1 of 1
Correct
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 6.0 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 240 engines and the mean pressure was 6.1
pounds/square inch. Assume the standard deviation is known to be 0.8. A level of significancesof 0.05 will be used. Determine the decision rule.
Enter the decision rule.
