Hello,

If I have a survey of 1102 teens, in which they collected data about video game used by teens.

Part of the data are as follows:

Genre Racing Puzzle Sports Percent who play 74, 72, 68

a) How do I construct a two-sided symmetric 90% confidence interval for estimating the population proportion ofsportsgame players, using normal approximation?

b)Can I reasonably perform a two sample test to compare the proportions ofracingandpuzzlegame players?

Please let me know.

Thanks!
