Answer:

C

Step-by-step explanation:

Hey There!

So the answer is C because essentially answer choice c is saying that you can predict what the amount of problems that the next kid would complete in 30 minutes because all of the samples have a mean of 15.6-15.9 or that all of the samples are reliable because all of the means are near each other

And if you didnt know the mean is the average of all of the numbers in the sample

There C is your answer

P ( not arraive) = 100% - 80%   Isolate the needed

20%, or 0.20, or 1/5
