A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 901 people age 15 or older, the mean amount of time spent eating or drinking per day is 1.85 hours with a standard deviation of 0.57 hour. Complete parts (a) through (d) below. Click the icon to view the table of critical t-values. 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.) OA. The nutritionist is 90% confident that the amount of time spent eating or drinking per day for any individual is between OB. The nutritionist is 90% confident that the mean amount of time spent eating or drinking per day is between OC. There is a 90% probability that the mean amount of time spent eating or drinking per day is between and and and hours. hours. hours. (d) Could the interval be used to estimate the mean amount of time a 9-year-old spends eating and drinking each day? Explain. O A. Yes; the interval is about individual time spent eating or drinking per day and can be used to find the mean amount of time a 9-year-old spends eating and drinking each day. OB. No; the interval is about individual time spent eating or drinking per day and cannot be used to find the mean time spent eating or drinking per day for specific age. OC. Yes; the interval is about the mean amount of time spent eating or drinking per day for people age 15 or older and can be used to find the mean amount of time spent eating or drinking per day for 9-year-olds. OD. No, the interval is about people age 15 or older. The mean amount of time spent eating or drinking per day for 9-year-olds may differ.
