Question

Twelve different video games showing alcohol use were observed. The duration times of alcohol use were recorded, with the times (seconds) listed below. What requirements must be satisfied to test the claim that the sample is from a population with a mean greater than 75 sec? Are the requirements all satisfied?

80, 13, 591, 46, 0, 55, 197, 46, 177, 0, 2, 52

What requirements must be satisfied? Select all that apply.

A. Either the population is normally distributed, or n>30 , or both

B. At least one observation must be above or below 75 sec.

C. The conditions for a binomial distribution must be satisfied.

D. The sample observations must be a simple random sample.

Are the requirements all satisfied?

A. No. The sample size is not greater than​ 30, the sample does not appear to be from a normally distributed​ population, and there is not enough information given to determine whether the sample is a simple random sample.

B. Yes. The conditions for a binomial distribution are​ satisfied, and there is enough information to determine that the sample is a simple random sample.

C. No. The conditions for a binomial distribution are not​ satisfied, and there is not enough information given to determine whether the sample is a simple random sample.

D. No. The sample size is not greater than​ 30, the sample does not appear to be from a normally distributed​ population, and there are no observations above

E. Yes. A normal quantile plot suggests that the sample is from a normally distributed​ population, and there are observations above and below

F. Yes. A normal quantile plot suggests that the sample is from a normally distributed​ population, and there is enough information to determine that the sample is a simple random sample.
