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. 1213
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"
Thanks,
