Hi,

I may find other issues later, but for now can you please check the answer choices for #11 and #12? Is there any possibility that the answer sets got switched around? The answer that I need for #11 is not present in the accompanying choices, but it is in the answers available for #12.

Thanks,

Ryan

Hi,

Here are the solutions:

10. B. 45

11. I don't have the definitive answer for this one. None of the answer choices are particularly good, and the height of a bar on a histogram is rather arbitrary anyway. If I had to select one, I would go with A. 4, as it is the least objectionable in my opinion.

12. B. 8.5

13. A. 12-13

14. E. 6, 100

15. A. 2

16. C. 39.88

17. B. 120.5

18. B. False

19. B. systematic error

20. A. greater

21. A. False

22. The actual value should be 85.91%. Answer B is the closest.

23. The answer that I got was 54.19%. Answer B is the closest.

24. E. Avg = 13, SD = 3

25. E. 6' 11"
