Let a and b be real numbers where a 4640. Which of the following functions could represent the graph below? Of(x) = x(x – a)2(x – 634
f(x) = x(x – a) (x - b)2
f(x) = AX - a)(x – b)2
F(X) = x2(x - a) 5(x – b)

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.
