75% of students at a College receive financial aid. We surveyed 110 randomly selected students.

a) Find the mean and standard deviation for the number of students in the survey that receive financial aid using the Binomial model.

b) Use binomcdf to determine the probability that at least 81 of the 110 students in the survey receive financial aid.

c) Approximate the Binomial with the Normal by using normalcdf to estimate the same probability as in Question b.
