Twelve different video games showing violencewere observed. the duration times of violencewere? 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 than80 sec? are the requirements all? satisfied? 83 13 572 49 0 58 195 41 165 0 2 59what 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 below80sec. c.the conditions for a binomial distribution must be satisfied. d.either the population is normally? distributed, orn 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 below8080sec. 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 above80sec. 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.
