A recent study of the hourly wages of maintenance crew members for major airlines showed that the mean hourly salary was $20.50, with a standard deviation of $3.50. Assume the distribution of hourly wages follows the normal probability distribution. We select a crew member at random.

What is the probability the crew member earns:

(a) Between $20.50 and $24.00 per hour (Round your answer to 4 decimal places.)

Probability

(b) More than $24.00 per hour (Round your answer to 4 decimal places.)

Probability

(c)
Less than $19.00 per hour (Round intermediate calculations to 2 decimal place. Round final answer to 4 decimal place)
