A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 1041 people age 15 or older, the mean amount of tim spent eating or drinking per day is 1.72 hours with a standard deviation of 0.67 hour. Complete parts (a) through (d) below. (D) There are more than 200 milion people nationally age 5 or vider. Explain why us, along with the fact that the data were obtained using a random sample, sausies une requirements for constructing a confidence interval. A. The sample size is less than 5% of the population. OB. The sample size is less than 10% of the population. OC. The sample size is greater than 5% of the population. OD. The sample size is greater than 10% of the population. (c) Determine and interpret a 95% 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.) and hours. O A. There is a 95% probability that the mean amount of time spent eating or drinking per day is between and hours. OB. The nutritionist is 95% confident that the amount of time spent eating or drinking per day for any individual is between OC. The nutritionist is 95% confident that the mean amount of time spent eating or drinking per day is between and hours. O D. The requirements for constructing a confidence interval are not satisfied.
