A New York Times article reported that a survey conducted in 2014 included 36,000 adults, with 3.71% of them being regular users of e-cigarettes. Because e-cigarette use is relatively new, there is a need to obtain today's usage rate. How many adults must be surveyed now if a confidence level of 90% and a margin of error of 1 percentage are wanted? a. Assume that nothing is known about the rate of e-cigarette usage among adults. n=? b.. Use the results from the 2014 survey. n=? c.. Does the use of the result from the 2014 survey have much of an effect on the sample size?
