A normal distribution has a mean of µ = 60 with σ = 5. If a vertical line is drawn through the distribution at X = 65, what proportion of the scores are on the left side of the line?

Scenario: I’m interested in whether there is a relationship between Team (A vs. B) and Outcome (Good vs. Bad). Below are the data.  Test the null hypothesis that the categories are independent.  α= .05. Team A Team B Good Outcome fo = 116 fe = fo = 84 fe = Bad Outcome fo = 64 fe = fo = 36 fe =   degrees of freedom, df = ______, and the Chi Square critical boundary = ______

Does training in meditation make a difference for student success?  10 students received training (M1= 88, SS1= 240) and 5 students did not (M2= 82, SS2= 150). Test using α = .05   The correct APA format for the result would include
