The heat evolved in calories per gram of a ce-ment mixture is approximately normally dis-tributed. The mean is thought to be 100 and the standard deviation is 2. We wish to test Ηο: μ = 100 versus H₁: μ≠ 100 with a sam-ple of n=16. If the acceptance region is define as 98.5 ≤ x ≤ 101.5, find the type I error prob-ability a.
Let P(Z-3) = 0.00135; P(Z ≤ 3) = 0.99865
