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.
