The self-serve juice machine at Burger King in Mall of Asia is strictly regulated such that the amount of juice dispensed is approximately normally distributed with a mean of 200 milliliters and a standard deviation of 12.5 milliliters. The machine is checked periodically by taking a sample of 9 drinks and computing the average content. If the mean falls in the interval 191 < x < 209, the machine is operating satisfactorily; otherwise, we conclude that µ # 200 milliliters. a) Find the probability of committing a type I error when µ = 200 milliliters. b) Find the probability of committing a type II error when μ = 215 milliliters.

Transcribed Image Text:2. The self-serve juice machine at Burger King in Mall of Asia is strictly regulated such that the amount
of juice dispensed is approximately normally distributed with a mean of 200 milliliters and a standard
deviation of 12.5 milliliters. The machine is checked periodically by taking a sample of 9 drinks and
computing the average content. If the mean falls in the interval 191 < x < 209, the machine is
operating satisfactorily; otherwise, we conclude that µ ‡ 200 milliliters.
