A machine in a large factory is designed to mill a small lawnmower engine part out of a solid piece of aluminum. The distribution of times that it takes the machine to mill a part is approximately normally distributed with a mean of 39.2 seconds with a standard deviation of 14.2 seconds. Let X = the amount of time required to mill the engine part out of a randomly selected piece of aluminum. Using the 68-95-99.7 rule, calculate P(X > 10.8).
