A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of

(a) A histogram of time spent eating and drinking each day is skewed right. Use this result to explain why a large sample size is needed to construct a confidence interval for the mean time spent eating and drinking each day.
