The scheduled arrival time for a dally flight from Boston to New York is 9:30 am. Historical data show that the arrival time follows the continuous uniform distribution with an early arrival time of 9:20 am and a late arrival time of 9:40 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.) minutes Mean Standard deviation minutes b. What is the probability that a flight arrives late (later than 9:30 am)? (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places) Probablity 0.50

    Question 2: (11 pts) A show is scheduled to start at 9 AM, 9.30 AM and 10 AM. Once the show starts, the gate will be closed. A visitor will arrive at the gate a time uniformly distributed between 8.30 AM and 10 AM. Determine (a) Probability density function of the time (in minutes) between arrival and 8.30 AM and plot. (b) Cumulative distribution function of the time (in minutes) between arrival and 8.30 AM and plot. (c) Mean and...

    Calculate the probability that a flight will depart early or on-time. P(flight early/on time DEPP)=(#flights early/on time)/(total # flights)=363/500= 0.726 Calculate the probability that a flight will arrive late. P(Late ARR)=(#flights late)/(total # flights)=170/500= 0.34 Calculate the probability that a flight departs late or arrives early (does not say on time). P(Late/early DEPP)=(#flights Late+ early)/(total # flights)=428/500= 0.856 If the above is correct, Assume now that the random variable X=Arrival Time is exactly normally distributed with mean m= -2.5 and...

    The EMS response time from a notification to the arrival of a crash site in an urban area has a mean of 6.8 minutes and a standard deviation of approximately 3 minutes. The population distribution is skewed right (positively skewed). a) If we looked into a random sample of 34 crashes in an urban area, then would it be reasonable to say that the sampling distribution of a sample mean, , will be approximately normal? Answer either yes or no....

    Among the thirty largest U.S. cities, the mean one-way commute time to work is 25.8 minutes. The longest one-way travel time is in New York City, where the mean time is 38.9 minutes. Assume the distribution of travel times in New York City follows the normal probability distribution and the standard deviation is 7.9 minutes. Use Appendix B.3. What percent of the New York City commutes are for less than 30 minutes? (Round your intermediate calculations and final answer to...

    An electronics manufacturing process has a scheduled mean completion time of 75 minutes. It is claimed that, under new management, the mean completion time, H, is less than 75 minutes. To test this claim, a random sample of 15 completion times under new management was taken. The sample had a mean completion time of 70 minutes and a standard deviation of 9 minutes. Assume that the population of completion times under new management is normally distributed. At the 0.05 level...

    Offwego Airlines has a daily flight from Chicago to Las Vegas. On average, 13 ticket holders cancel their reservations, so the company intentionally overbooks the flight. Cancellations can be described by a normal distribution with a mean of 13 passengers and a standard deviation of 5.30 passengers. Profit per passenger is $93. If a passenger arrives but cannot board due to overbooking, the company policy is to provide a cash payment of $193. Use Table B. How many tickets should...

    An electronics manufacturing process has a scheduled mean completion time of 65 minutes. It is claimed that, under new management, the mean completion time, is less than 65 minutes. To test this claim, a random sample of 18 completion times under new management was taken. The sample had a mean completion time of 6 minutes and a standard deviation of 8 minutes. Assume that the population of completion times under new management is normally distributed. At the 0.05 level of...

    The wait time (after a scheduled arrival time) in minutes for a train to arrive is Uniformly distributed over the interval [0, 12]. You observe the wait time for the next 100 trains to arrive. Assume wait times are independent. Part a) What is the approximate probability (to 2 decimal places) that the sum of the 100 wait times you observed is between 565 and 669? Part b) What is the approximate probability (to 2 decimal places) that the average of the...
