Full-time Ph.D. students receive an average of $12,837 per year. If the average salaries are normally distributed with a standard deviation of $1500, find:
B) the probability that a student makes between $13,000 and
$14,000.
(C) the interquartile range for the salaries.
(D) the salaries belonging to the 10th and 90th percentiles. (Be
sure you calculate both values!)
B I know is 0.2385 (correct answer)
I'm having a hard time with C and D. Can you also please provide the equations needed? would be a big help thank you.
