Common Sense Media surveyed 1000 teens and 1000 parents of teens to learn about how teens are using social networking sites such as Facebook and Instagram. The two samples were independently selected. When asked if they check their online social networking sites more than 10 times a day, 220 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, 40 said yes. Conduct a hypothesis test at the alpha = 0.10 level to test whether there is a difference in the proportion of teens and parents who check their online social networking sites.
