SUD A nutritionist wants to determine how much time nationally people spend eating and drinking Suppose for a random sample of 1021 people age 15 or older, the mean amount of time spent eating or drinking per day with a standard deviation of 0.73 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 O A. The distribution of the sample mean will always be approximately normal O B. Since the distribution of time spent eating and drinking each day is not normally distributed (skewed right), the sample must be large so that the distribution of the sample mean will be approximately normal O C. The distribution of the sample mean will never be approximately normal. O D. Since the distribution of lime spent eating and drinking each day is normally distributed, the sample must be large so that the distribution of the sample mean will be approximately normal (b) There are more than 200 million people nationally age 15 or older Explain why this, along with the fact that the data were obtained using a random sample, satisfies the requirements for constructing a confidence O A. The sample size is less than 10% of the population O B. The sample size is less than 5% of the population O C. The sample size is greater than 5% of the population, O D. 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.
