Another company is also interested in the amount game consumers spend, and surveys a random sample of 250 of its top gamer and finds that the average gamer spends $250 a year on games, with a standard deviation of $15. Why is the second survey more believable than the first. A. the likelihood of those in the first survey to lie about the amount they spend. B the spend of the confidence interval for the second survey. C. the sizes of the sample for the second survey. D. the lack of randomization in the first survey
