What requirements must be? satisfied? Select all that apply.

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

B. At least one observation must be above or below 80 sec.

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

D. Either the population is normally? distributed, or n greater than>?30, or both.

Are the requirements all? satisfied?

A. Yes. A normal quantile plot suggests that the sample is from a normally distributed? population, and there are observations above and below 8080 sec.

B. 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.

C. 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 80 sec.

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

E. 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.

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.
