Suppose two events A and B are independent, with P(A) โ 0 and P(B) โ 0. By working through the following steps, you'll see why two independent events are not mutually exclusive. (a) What formula is used to compute P(A and B)? P(A) + P(B) P(A) / P(B) P(A) โ P(B) P(A) ยท P(B) Is P(A and B) โ 0? Explain. Yes. Even if P(A) = 0 or P(B) = 0, P(A and B) will always be non-zero. No. Because both P(A) and P(B) are not equal to 0, P(A and B) = 0. No. P(A and B) = 0. Yes. Because both P(A) and P(B) are not equal to 0, P(A and B) โ 0. (b) Using the information from part (a), can you conclude that events A and B are not mutually exclusive? No. Two events being independent always implies they are mutually exclusive. No. Because P(A and B) โ 0, A and B are mutually exclusive. Yes. Two events being independent always implies they are mutually exclusive. Yes. Because P(A and B) โ 0, A and B are not mutually exclusive.

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.
