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 DX is normally distributed 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. P(2.9 < X <3.1) Sample size Standard deviation Distribution = Mean . 2.886 2.9 t X 1 Find the probability that the sample mean is between 2.9 hours and 3.1 hours.
