... (b) At Berkeley, there are about 26,000 undergraduates and about 10, 000 graduate students. Suppose you only want to understand the frequency of sitting-in for the undergraduates. If you want to obtain an estimate with error of at most 5% with 98% confidence, how many undergraduate students would yo ...
