B. if the distribution of time spent on the job is approximately bell shaped, between what two times would 95% of the figures be?

C. if the distribution of time spent on the job is approximately bell shaped, between what two times would 99.7% of the figures be?

D. if the shape of the distribution of times is unknown, approximately what percentage of times would be between 358 and 480 minutes? (round the intermediate value to 3 decimal places. Round your answer to 1 decimal place)

E. suppose a worker spent 400 minutes on the job. what would that workers z score be, and what would it tell the researcher? (round your answer to 3 decimal places)

F. this worker is in the lower half of workers but within WHAT standard deviation of the mean?
