When asked if they check their online social networking sites more than 10 times a day, 226 of the teens surveyed said yes. When parents of teens were asked if their teen checked his or her site more than 10 times a day, 49 said yes. Use a significance level of 0.01 to carry out a hypothesis test to determine if there is convincing evidence that the proportion of all parents who think their teen checks a social networking site more than 10 times a day is less than the proportion of all teens who report that they check more than 10 times a day. (Use pteens − pparents. Round your test statistic to two decimal places and your P-value to four decimal places.)
