[Example continued…] The average YouTube user spends 40 minutes per session, using YouTube (μ = 40), and σ is unknown. Test whether ARC students who are YouTube users (n = 16, M = 38, SS = 960) differ from the average YouTube user on number of minutes spent using YouTube per session. α = .05. The critical t score boundaries =
