Question

Solve the problem. 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 2% with 95% reliability, how many students would need to be sampled? 1186 562 2324 47

Step 1

645 * sqrt((0.59 * 0.41) / 200) Margin of error = 1.645 * sqrt(0.2369 / 200) Margin of error = 1.645 * sqrt(0.0011845) Margin of error ≈ 1.645 * 0.0344 Margin of error ≈ 0.0566 Show more…
