The length of time, in hours, it takes an "over 40" group of people to play one soccer match is normally distributed with a mean of 3 hours and a standard deviation of 0.4 hours. A sample of size n = 50 is drawn randomly from the population. Check off the following that are true. At least one must be true. On > 30 Complete the following table for the distribution of X and X. Round the standard deviation of X (standard error of the mean) to four decimal places. Sample size Mean Standard deviation Distribution P(2.9 < X < 3.1) 2.886 OX is normally distributed 2.9 * 2.943 X 1 3 0.4 Find the probability that the sample mean is between 2.9 hours and 3.1 hours.
