Assume that the weight of cereal in a 10-ounce box is N(, 2 ). To test

Question:

Assume that the weight of cereal in a “10-ounce box” is N(μ, σ2). To test H0 : μ = 10.1 against H1 : μ > 10.1, we take a random sample of size n = 16 and observe that ¯x = 10.4 and s = 0.4.

(a) Do we accept or reject H0 at the 5% significance level?

(b) What is the approximate p-value of this test?
