American eat out very frequently; the average American adult buys a meal or snacks from a restaurant 5.8 time a week (The United State Healthful Food Council, December 5, 2015). Assume the standard deviation for the number of meals or snacks American adults buy from restaurants per week is 1.5. Suppose you would like to conduct a survey to develop a 95% confidence interval estimate of the number of meals or snacks American adults buy from restaurants per week. A margin of error of 0.5 is desired. Choose a sample size that would guarantee that the margin of error will not exceed 0.5? 25 35 20 10
