In a marketing class, 44 student members of virtual (Internet) project teams (group 1) and 42 members of face-to-face project teams (group 2) were asked to respond on a 1­5 scale to the question: "As compared to other teams, the members helped each other." For group 1 the mean was 2.73 with a standard deviation of 0.97, while for group 2 the mean was 1.90 with a standard deviation of 0.91. At α = .01, is the virtual team mean significantly higher? (Data are from Roger W. Berry, Marketing Education Review 12, no. 2 [2002], pp. 73­78.)
