A machine is designed to fill 18-ounce bottles of shampoo. When the machine is working properly, the amount poured into the bottles follows a Normal distribution with mean 18 ounces and standard deviation 0.4 ounce. Assume that the machine is working properly. What is the probability that a simple random sample of 15 bottles has a mean of 18.2 ounces or more?
