A study of Saturday arrival times showed that the average arrival time was 3 hours and 48 minutes after the doors opened, and the standard deviation was estimated at about 53 minutes. Assume that the arrival times follow a normal distribution. m USES (a) At what time after the doors open will 94% of the people who are coming to the Saturday show have arrived?
