(b) Suppose that Crown Bottling Company decides to use a level of significance of α = 0.01, and suppose a random sample of 34 bottle fills is obtained from a test run of the filler. For each of the following four sample means— x¯ = 16.06, x¯ = 15.97, x¯ = 16.02, and x¯ = 15.91 — 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. (Round your z to 2 decimal places and p-value to 4 decimal places and CI to 3 decimal places.) x¯ = 16.06 x¯ = 15.97 x¯ = 16.02 x¯ = 15.91
