Suppose that on a statistics test the mean greade in a class is 75 and the population standard deviation is 8. Assume that the distribution of grades is bell-shaped.

(a) What percent of students recieved grades between 59 and 91?

(b) What percent of students will reveive grades below 83?

(d) If 700 students took the course, how many had a score above 99?

Please show all work and explain if you can how you get the answers.
