A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than examining the records for all students, the dean randomly selects 400 students and find that 236 of them are receiving financial aid. а. If the dean wanted to estimate the proportion of all students receiving financial aid to within 4% with 95% reliability, how many students would be needed to be sampled? b. Suppose the dean wants the width and hence the sampling error to be doubled of the size that
