Answer #1

Let  X denotes the number of students in a random sample of size 50 who receive financial aid.

25% of all students at a large public university receive financial aid.

We have

As we have used normal to approximate binomial

the probability that at most 10 students receive aid is 0.2568

A university dean states that the proportion of students who receive some sort of financial aid has increased compared to 55% of students who received financial aid over the last several years. The dean randomly selects 200 students and finds that 118 of them are receiving aid. Form the hypothesis to test the dean’s statement. Conduct this test and explain if you support the dean’s statement using 5% significance level for this test.

A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 122 of them are receiving financial aid. Use a 95% confidence interval to estimate the true proportion of students who receive financial aid.

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.

A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. If the dean wanted to estimate the proportion of all students receiving financial aid to within 1% with 98% reliability, how many students would need to be sampled?

Rather than examine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. If the dean wanted to estimate the proportion of all students receiving financial aid to within 3% with 99% reliability, how many students would need to be sampled?
