The GPAs of all students enrolled at a large university have an approximately normal distribution with a mean of 3.02 and a standard deviation of 0.29. Find the probability that the mean GPA of a random sample of 20 students selected from this university is 2.92 to 3.11. Round your answer to four decimal places. P (2.92 ? x? ? 3.11) =
