C. 19.42% because you subtract 389.85 from 314.15 which equals 75.7. So then set it up like an algebraic equation. 389.85x=75.7 divide 75.7 by 389.85 to find the decimal. Then you have to move the decimal to the right two places, since it is a percentage. And then round your answer, so c. 19.42% is your answer. Hope this helped! :)

Step-by-step explanation:
So what are u trying to say here. She read in 1/20 of what, minutes, seconds, or what
Data:
15 16 14 15 19 17
n=6 points
sum is 96
mean is 96/6 = 16
Now we look at the absolute deviations, each of which is the absolute value of a score minus the mean, basically the distance of the score to the mean .
Scores 15 16 14 15 19 17
AbsDev 1 0 2 1 3 1
The sum of the absolute deviations is 8 and there are six of them so the
Mean Absolute Deviation = 8/6 = 4/3
Answer: 2. 8/6
