A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wishes to test Ho:μ = 198 millimeters versus H₁: > 198 millimeters, using the results of n = 12 samples. Round your answers to three decimal places (e.g. 98.765). (a) Find the type I error probability az if the critical region is * > 208. a = (b) What is the probability of type II error if the true foam height is 208 millimeters? B = i (c) Find for the true mean of 218 millimeters. B =
