mount of time that a drive-through bank teller spends on a customer is a random variable with a mean p = 5.5 minutes and a standard deviation o = 3.0 minutes. If a random sample of 36 ners is observed, find the probability that their mean time at the teller's window is most 4.4 minutes; re than 6.2 minutes, east 5.5 minutes but less than 6.3 minutes. here to view page 1 of the standard normal distribution table. here to view page 2 of the standard normal distribution table. e probability that the mean time is at most 4.4 minutes is d to four decimal places as needed.) e probability that the mean time is more than 6.2 minutes is d to four decimal places as needed.) probability that the mean time is between 5.5 minutes and 6.3 minutes is d to four decimal places as needed.)
