Question

A video game company surveys a random sample of 250 gamers who report annual income of $50,000. The company finds that the average gamer spends $206 a year on games, with a standard deviation of $12.

Another company is also interested in the amount game consumers spend, and surveys a random sample of 225 gamers with a verified yearly income of $50,000. The company 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?

Answer 1

A. size of the confidence interval for the second survey
B. lack of randomization in the first survey
C. likelihood of those in the first survey to lie about the amount they make
D.size of the sample for the second survey

Answer 2

what do you think?

Answer 3

C maybe?

Answer 4

yes I would go with C as well because in the first survey the people themselves say 50,000 and in the second survey, the company finds people who actually make 50,000
