Answer:
8/27 is represented in decimal as 0.2962962963
A. I’m not sure what this is asking but I’d guess 8,9,10
B is 19,20,21
C is there is none
To do that you'll need the mean and standard deviation of all the scores. Can you provide this info?
For example: Supposing that the mean of these scores were 52 and the standard deviation 3. You'd need to find the "z-score" of 57 in this case.
57 - 52
It is z = ------------ , or z = 5/3, or z = 1.67.
3
Find the area to the left of z = 1.67. Multiply that area by 100% to find the percentile rank of the score 57.
160/3 is 53 1/3 as a fraction
