Suppose that the population mean flight time between cities 1 and 2 is 150 minutes with a population standard deviation of 28 minutes, and that this trip time is a Normally distributed random variable. Find the trip time in minutes that would only be exceeded with a 0.05 probability (or a 5% chance).

    QUESTION 5 A bus company advertised a mean time of 150 minutes for a trip between two cities. A consumer group had reason to believe that the mean time was more than 150 minutes. A sample of 40 trips showed a mean ˉx=153 minutes and a standard deviation s=7.5 minutes. At the 0 .05 level of significance, test the consumer group’s belief.

    given an airline that flies between two cities with a quoted flight time of 2 hours and 10 minutes(130 minutes). Historical records indicate that the flight time between the two cities varies from 2 hours (120 minutes) to 2 hours and 20 minutes (140 minutes). The flight times are uniformly distributed. What is the probability that the flight will be at least 5 minutes late?
