A normal distribution has μ = 9 and σ = 2. What is the probability of a score greater than 6 from this distribution, p(X > 6)?

[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. t =     (test statistic)

[Example continued…] The personality trait of “Conscientiousness” (someone who is organized, responsible, and can control their impulses) has μ = 120 and σ =9. Test whether ARC students (n = 9, M = 126) differ on Conscientiousness. α = .05. Does the z score for the sample mean lie in the critical region (beyond the critical boundary)?

What is the correct conclusion based on the following ANOVA result: [F(3,16) = +1.77, p > .05]

[example continued…] Given the following data: SP = 50; SSX = 25; MY = 150; MX = 12 Predict Ŷ given X = 2

Given the following data: SP = 50; SSX = 25; MY = 150; MX = 12 The slope, b = 

[example continued…] Does training in stress reduction make a difference for student success?  15 students received training (M1= 88, SS1= 400) and 15 students did not (M2= 82, SS2= 440). Test using α = .05   s(M1-M2) = 

[example continued…] Given the following data: SP = 50; SSX = 25; MY = 150; MX = 12 The y intercept, a = 

[example continued…] Is there a difference among the 3 treatments in the table below?  Test using α = .05 Treatment A Treatment B Treatment C 2 3 2 ∑X2 = 280 2 3 4 G = 60 3 4 5 N = 15 3 5 6 k = 3 5 5 8 SS1 = 6 SS2 = 4 SS3 = 20   MSbn = ______ MSwn = ______

[example continued…] Below is data for two variables, X and Y.  Answer the questions that follow.  X Y X-MX Y-MY (X-MX)2 (Y-MY)2 (X-MX)(Y-MY) 3 3 -2 -1 4 1 2 4 3 -1 -1 1 1 ___ 6 4 1 ___ 1 0 0 7 6 2 2 ___ 4 4   What is the missing value under the Y-MY column?
