Twelve different video games showing drug use were observed. The duration times of drug 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 80 sec? Are the requirements all satisfied?

87, 13, 545, 51, 0, 55, 218, 41, 184, 0, 2, 52

What requirements must be satisfied? Select all that apply.

A. The sample observations must be a simple random sample.
B. The conditions for a binomial distribution must be satisfied.
C. At least one observation must be above or below 80 seconds.
D. Either the population is normally distributed, or n>30, or both.
