(1 point) Suppose we want a 99% confidence interval for the average amount spent on books by freshmen in their first year at college. The amount spent has a normal distribution with standard deviation $33. (a) How large should the sample be if the margin of error is to be less than $3? ANSWER: sample. (Enter: "LARGER", "SMALLER" or (b) If we wanted a smaller margin of error, we would need a "SAME SIZE", without the quotes.)
