For air travelers, one of the biggest complaints is of the waiting time between when the airplane taxis away from the terminal until the flight takes off. This waiting time is known to have a right skewed distribution with a mean of 10 minutes and a standard deviation of 8 minutes. Suppose 10000 flights have been randomly sampled. Describe the sampling distribution of the mean waiting time between when the airplane taxis away from the terminal until the flight takes off for these 10000 flights.

Let’s say the table below shows the proportion of all domestic phone calls in the United States split into categories of the duration of calls. Of a sample of 1000 calls, what proportion of those calls would we expect to last 30 minutes and more? Time in Minutes Proportion of All Calls 0 but less than 5 .37 5 but less than 10 .22 10 but less than 15 .15 15 but less than 20 .10 20 but less than 25 .07 25 but less than 30 .07 30 and more .02
