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 4% with 90% reliability, how many
students would need to be sampled? Select one: a. 99 b. 249 c. 17
d. 410
