Explanation / Answer

19. D. The number of standard deviations a number is from the mean of the distribution

20. C. Is the probability that an event will occur based on the fraction of times a similar event occured in the past.

21. number of ways possible = 49C6 = 13,983,816 (option B)

22. A. P(A) = 1 - P(~A)

23. Data in ascending order

75,79, 80, 84, 88, 90, 92, 95, 100

5 number summary is - 75, 79.5, 88, 93.5, 100 (option B)

24. Number of models possible = 26x10x10 = 2600(option D)
