The waiting time a customer spends in the airport luggage check-in is a random variable with mean8.2 minutes and standard deviation 1.5 minutes. Suppose that a random sample of n= 40 customerswere observed. Find the probability that the average waiting time in queue for customers is less than8 minutes. Would the probability change if airport management further shortens the queuing time ofcustomer less 7.5 minutes? Explain and include your solutions.O a. Probability is about 20%. Probability would decrease if queuing time were shortenedO b. Probability is about 20%. Probability will not change even if queuing time is reducedO. Probability will change if the queuing time is improved to less 7.5 minutesO d. NONE

A company offers guided tours of remote areas of the world. Each tour consists of 20 people. The probability of selling a ticket for any given spot on the tour is 0.86. The costs to the company are approximately the same regardless of the number of people that show up. To offset the risk associated with a tour not filling up, the company purchases a specialized insurance policy. The policy pays 100 for each ticket that is left unsold, up to a maximum of 400. Let P be the amount that the insurance policy pays to the company for a specific tour. Calculate E[P] to the nearest dollar. O 251 O244 O 259 O 267 275
