The pew internet and american life project reported wednesday, april 18th that two- thirds (67%) of young adults with profiles on social-networking sites have restricted access to their profiles by requiring passwords or making them available only to friends on an approved list ("study: teens protecting their profiles" posted: 10: 54 a. m. edt, april 19, 2007 on cnn. com). a researcher believes that military personnel are more careful with keeping themselves safe online and surveys a random sample of 100 enlisted military personnel students and finds that 78 students restrict access to their profiles. does this indicate at the 5% significance level that a larger proportion of military personnel protect their profiles on social-networking sites?
