The length of time, in hours, it takes an "over 40" group of people to play one soccer match is normally distributed with amean of two hoursand astandard deviation of 0.5 hours. Asample of sizen= 50is drawn randomly from the population. Find the probability that thesample meanis between 1.8 hours and 2.3 hours.

Calculate the standard deviation from the CLT (Central LimitTheorem) to4places.

For your answer, go to the 3th decimal place. For example: 0.000
