A pizza chain records how long it takes customers to receive their delivery orders. Suppose the distribution of these delivery times is strongly skewed to the left with a mean of 303030 minutes and a standard deviation of 101010 minutes. Management plans on calculating the mean delivery time from a random sample of 252525 orders. We can assume independence between orders in the sample. What is the probability that the mean delivery time from the sample of 252525 orders \bar x x ˉ x, with, \bar, on top is farther than 222 minutes from the population mean? Choose 1
