The scheduled arrival time for a daily flight from boston to new york is 9: 25 am. historical data show that the arrival time follows the continuous uniform distribution with an early arrival time of 9: 07 am and a late arrival time of 9: 47 am. a. after converting the time data to a minute scale, calculate the mean and the standard deviation of the distribution. (round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) b. what is the probability that a flight arrives late (later than 9: 25 am)? (round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.)
