A recent study of the hourly wages of crew members for major airlines showed that the mean hourly salary was P20.00 with a standard deviation of P3.50. Assume the distribution of the hourly wages follows the normal probability distribution. If we select a crew member at random, what is the probability the crew member earns: a. Between P21.50 and P24 per hour? b. More than P25 per hour? c. Less than P19.50 per hour?
