Exercise 8-51 Algo

An accounting professor is notorious for being stingy in giving out good letter grades. In a large section of 80 students in the fall semester, she gave out only 6% A's, 16% B's, 51% C's, and 27% D's and F's. Assuming that this was a representative class, compute the 90% confidence interval of the probability of getting at least a B from this professor.
