(a) Compute the z value associated with 24.0. (Round your answer to 2 decimal places.) z
(b) What proportion of the population is between 20.0 and 24.0? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)
Proportion
(c) What proportion of the population is less than 15.0? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.)
