Assume that the weight of cereal in a "10-ounce box" is N( µ, ai). To test H0 : µ = 10.l against H1 : µ > 10.1, we take a random sample of size n = 16 and observe that = 10.4 and s = 0.4.
(a) Do we accept or reject H0 at the 5 percent significance level?
(b) What is the approximate p-value of this test?
