Answer 16- for Class orange, Case id-dik, unots away from the mean according giren Conditions. tor Class Apple, Case id- a, b, k, d, Units of S.D away from the mean according given Conditions Answer 17- Answer 18 - Case id - aik, that fall mose than 1.5 Units of S.D away from the mean for Class orange. Answer 19 - Case id - aib; k, l, that fall more than is Units of SD away from the mean for Class Apple. Answer 20 - for Class range Range - 0 to 100 points Mean = 50 S.D = 19.494 for Class apple - Range so to 200 points mean = 137.5 S'D = 23.404 Now for Class range, for Class Apples 7: -1, X = x - 4, 2= 100-50 Z = 200- 1375 19.494 23. 404 7:2.565 3. D above mean 7 -2.671 S.D above mean Here Z-score of Class change is better than Class apple because of lass value Contain and also have smalt less than Standard deviation.
