Question:
a. The bottling company wants to set up a hypothesis test so that the filler will be readjusted if the null hypothesis is rejected. Set up the null and alternative hypotheses for this hypothesis test.
b. Suppose that Crown Bottling Company decides to use a level of significance of α = .01, and suppose a random sample of 36 bottle fills is obtained from a test run of the filler. For each of the following four sample means- = 16.05,1 = 15.96, = 16.02, and = 15.94-determine whether the filler's initial setup should be readjusted. In each case, use a critical value, a p-value, and a confidence interval. Assume that σ equals .1.
