I just came across this forum because I need some help with a homework assignment. Hello to all.
I am terrible at math but need to take an intro statistics course. Could someone please help me with the below question?
The average full-time faculty member in a post-secondary degree-granting institution works an average of 53 hours per week.
a. If we assume the standard deviation is 2.8 hours, what percentage of faculty members work more than 58.6 hours?
b. If we assume a bell-shaped distribution, what percentage of faculty members work more than 58.6 hours a week?
I figure for a. I need to use Chebyshev's theorem and for b. the empirical rule, but beyond that, I am stuck at least in terms of figuring out the steps to figure out the answers. As I said, I am not very good with math.
Please help. The homework is due on Monday. Thank you very much.
