A set of n = 25 pairs of scores (X and Y values) has a Pearson correlation of r(23) = .60. How much of the variability among the Y scores is predicted by the relationship with X?

If the following seven scores are ranked from smallest (#1) to largest, then what rank should be assigned to a score of X = 1?Scores:  1, 1, 1, 1, 3, 6, 6, 6, 9

If an entire population with µ = 60 and σ = 8 is transformed into z-scores, then the distribution of z-scores will have a mean of ____ and a standard deviation of ____.

What is the value of ΣX + 1 for the following scores?  Scores: 1, 6, 3

Calculate the regression equation with the following information: SP = 101.43, SSx = 154.56, My = 11.52, and Mx = 12.13

Two samples from the same population both have M = 84 and s2 = 20; however, one sample has n = 10 and the other has n = 20 scores.  Both samples are used to evaluate a hypothesis that µ = 80 and to compute Cohen’s d.  How will the outcomes for the two samples compare?
