Question: A machine that fills cereal boxes is supposed to be calibrated so that the mean fill weight is 12 oz. Let denote the true

A machine that fills cereal boxes is supposed to be calibrated so that the mean fill weight is 12 oz. Let μ denote the true mean fill weight. Assume that in a test of the hypotheses H₀ :μ = 12 versus H₁ :μ = 12, the P-value is 0.30.

a. Should H₀ be rejected on the basis of this test? Explain.

b. Can you conclude that the machine is calibrated to provide a mean fill weight of 12 oz? Explain.
