Quiz score of the student whose score least fit the general pattern of data means the point which has the maximum error % or is farthest from the line of best fit!

So the point plotted on 5 hours has the maximum error and has 5.5 quiz score against it

Hence, option B

But 5.5 is also the score of first student whose score fits well with the general pattern of data?!

Sure it is, but it lies closer to the line of best fit!

1st student's error% = (6.1−5.55.5)(100)=10.90%

9th student's error% = (7.5−5.55.5)(100)=36.36%
