order to estimate the overall proportion of students who favor a shorter semester system, we selected a simple random sample of 36 students and found that 24 of them favor a shorter semester system. (a) Construct a 90% confidence interval for the overall proportion of students who favor a shorter semester system. (b) Find the margin of error associated with this c.i. and interpret the answer in plain language. (c) In order for the margin of error to be no greater than 0.1 (or 10 percentage points), how large a sample should be drawn instead?
