Question

9.25: Consider the trash bag case. The mean and the standard deviation of the sample of n = 40 trash bag breaking strengths are _ = 50.575 and s = 1.6438. Test H0 : µ = 50 versus Ha : µ > 50 by setting a equal to .05 and using a critical value rule. Also, interpret the (computer calculated) p-value of .0164 for the test.
