Calculate the standard deviation by getting the average of the average (mean) of the numbers. So the average of 43 for the governors is 5.916 and the average of 44 for the CEOs is 10.954. c) Judging from the results we can see that the CEOs have bigger desks than the governors.

a) z (340) = (340-300)/20 = 40/20 = 2 b) z(310) = (310-300)/20 = 10/20 = .5 c) z(260) = (260-300)/20 = -40/20 = -2 Raw Scores d) z = 2.4 score = 300 + 20 x 2.4 = 300 +48 = 348 e) z = 1.5 score = 3000 + 20 x 1.5 = 300 + 30 = 330 f) z = 0 , score = 300 g) z = -4.5 , score = 300 + 20 x -4.5 = 300 -90 = 210 15. z(81) = (81-50)/2 = 31/20 = 1.55, z(6.4) = (6.4-0)/5 = 1.28. So, the verbal ability adjudicate is higher. You need to figure this out by standardizing both scores by converting them to Z scores. 22. a) Its a non-random sample because non-random samples are express mail because they are not as representative of the population youre analyze as random samples are....
