A study recorded the duration times of violent video games observed, with times listed in seconds. To test the claim that the sample has a mean greater than 85 seconds from the population, several requirements must be satisfied: 1) the sample observations must be from a simple random sample, 2) the population must be normally distributed or the sample size must be greater than 30, or both, and 3) at least one observation must be above or below 35 seconds.

1. Tweive different visoo games showing volence wore observed. The ouration times of volence
were rocorded; with the times (seconde) Isted below. What ragairemerts must be satisfied to test
the ciaim that the sameie is from a population with a mean greater than 85 sec? Are the
requiromests all sabsiect? What requirements must to satisfied? Select all that acply. A. The
conditions for a binamial diatribuion must be satisfed D. At least one observation munt be above
or betow 35 sec. c. Father the popuation is normalyy distributed, or n>30, or both. D. The sample
observations must be a simple random sampie.
