[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 = 45, SS = 6000) differ from the average YouTube user on number of minutes spent using YouTube per session. α = .05. Based on this data, we could be making a ____ error. Based on this data, we should conclude that ARC students ______ from the average YouTube user.

[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 = 45, SS = 6000) differ from the average YouTube user on number of minutes spent using YouTube per session. α = .05. The correct APA format for the result would be
