The time to complete a survey is normally distributed with a mean of 30 minutes and standard deviation of 5 minutes. A sample of 25 people was randomly selected to complete surveys. The probability that the sample mean will exceed 31 minutes is being asked for. The central limit theorem applies because the sample size is large (n=25).
