A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 1047

1047 people age 15 orolder, the mean amount of time spent eating or drinking per day is 1.06

1.06 hours with a standard deviation of 0.72

0.72 hour. Complete parts (a) through (d) below.

(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.
