A New York Times article reported that a survey conducted in 2014 included 36,000 adults, with 3.68% 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 3 percentage points are wanted? Complete parts (a) through (c) below. a. Assume that nothing is known about the rate of e-cigarette usage among adults. n = 752 (Round up to the nearest integer.) b. Use the results from the 2014 survey. n= (Round up to the nearest integer.)
