Question

A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 1085 people, age 15 or older, the mean amount of time spent eating or drinking per day is 1.11 hours with a standard deviation of 0.59 hour Complete parts through below Since the distribution of time 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. 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. The distribution of the sample mean will always be approximately normal In 2010, there were over 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 interval. The sample size is less than 5% of the population. The temple sue is greater than 5% of the population. The sample size is less than 10% of the population. The sample size is greater than 10% of the population.

Explanation / Answer

The 10% condition states that sample sizes should be no more than 10% of the population

C is the right answer
