Which equation in point-slope form contains the point (2, 3) and has slope 2? a. y + 2 = 2(x + 3) b. y – 3 = 2(x – 2) c. y – 2 = 2(x – 3) d. y + 3 = 2(x + 2)

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
