The amount of time that a drive‐through bank teller spends on a customer is a random variable with a mean of 6.7 minutes and a standard deviation of 3.2 minutes. If a random sample of 64 customers is observed, find the probability that their mean time at the teller’s window is: At least 6.7 minutes but less than 7.3 minutes
