A soft-drink machine is regulated so that it discharges an average of 6.8 ounces per cup. The amount of drink is normally distributed with a standard deviation equal to 0.6 ounces, Part 1: (3 points ) What is the probability that a cup will contain more than 7.72 ounces? Part 2: (3 points ) What is the probability that a cup contains between 6.72 and 7.06 ounces?Part 3: (4 points ) Suppose we want to regulate this machine so that only 5% of the drinks go above a certain value. What should be that cut off value for this soft-drink machine?Part 4: The machine is checked periodically by taking a sample of 9 drinks and computing the average content. If falls in the interval , the machine is thought to be operating satisfactorily, otherwise, we conclude that ounces. i) (3 points ) Find the probability of committing a Type I error when ounces. ii) (3 points ) Find the probability of committing a Type II error when ounces.
