Show ALL work neatly, Need it ASAP, Will UPVOTE for sure

A soft-drink machine is regulated so that it discharges an average of 6.5 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 7.45 ounces?

Part 2:  (3 points )  What is the probability that a cup contains between 6.45 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.
