The Dean of Students at ACME University wants to estimate the proportion of students who cheated on a major exam. Previous studies at other universities indicate this proportion is less than 65.7% How many students does the Dean need to select in the sample in order to be 95% confident that the sample proportion is within two percentage points of the actual proportion who cheated, if the Dean thinks ACME students have more integrity than students at other universities. (Hint: Don’t use 0.657 in your calculations)
