An airline is studying the average length of time that each plane spends on the ground at an airport. The plane's ground stays have an unknown distribution with a mean of 48 minutes and a standard deviation of 22 minutes. A sample of 50 planes is randomly taken from the population. Use a calculator to find the probability that the average plane's ground stay for the sample will be greater than 55 minutes.
