A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 962 people age 15 or older, the mean amount of time spent eating or drinking per day is 1.45 hours with a standard deviation of 0.72 hour. Complete parts (a) through (d) below. A. The sample size is greater than 10% of the population. B. The sample size is less than 10% of the population. C. The sample size is less than 5% of the population. D. The sample size is greater than 5% of the population. (c) Determine and interpret a 99% confidence interval for the mean amount of time Americans age 15 or older spend eating and drinking each day. Select the correct choice below and fill in the answer boxes, if applicable. in your choice.

Question
A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random
sample of 962 people age 15 or older, the mean amount of time spent eating or drinking per day is 1.45 hours with a
standard deviation of 0.72 hour. Complete parts (a) through (d) below.
A. The sample size is greater than 10% of the population.
B. The sample size is less than 10% of the population.
C. The sample size is less than 5% of the population.
D. The sample size is greater than 5% of the population.
(c) Determine and interpret a 99% confidence interval for the mean amount of time Americans age 15 or older spend
eating and drinking each day.
Select the correct choice below and fill in the answer boxes, if applicable, in your choice.
(Type integers or decimals rounded to three decimal places as needed. Use ascending order.)
O A. The nutritionist is 99% confident that the mean amount of time spent eating or drinking per day is between
and hours.
OB. The nutritionist is 99% confident that the amount of time spent eating or drinking per day for any individual is
between and hours.
O C. There is a 99% probability that the mean amount of time spent eating or drinking per day is between and
hours.
D. The requirements for constructing a confidence interval are not satisfied.
