The Next Questions Are Based On The Following Information:
A hydraulic press is operating correctly when the standard deviation of the pressure is less than 120 pounds-per-square-inch (psi) .Suppose you take a random sample of 15 measurements throughout the day of the psi and find the standard deviation to be 148.Suppose you want to test whether the press is operating correctly.
-Assume the following null and alternative hypotheses: H0 : μ = μ0 and H1 : μ > μ0.In addition,you know σ.Take a random sample of n observations and choose some value α.What is the decision rule for this test?
