Answer :

(i) As per the question,


To find the mean of the points scored by A to find its average


Now,


Scores of A are = 14, 16, 10, 10


Hence,


Mean score =


=


=


= 12.5


Therefore,


Mean score is 12.5.


(ii) Here,


As per the question,


We have to find the digit with which the total points of C needs to be divided in order to find the mean number of points per game for C.


Now,


We know that,


Mean =


And,


We also know that C played total of 3 games


Hence,


The total points will be divided by 3, in order to find the mean of the number of points per game for C.


(iii) As per the question,


We have to find the mean of the points scored by B to find its average


Now,


Scores of B are = 0, 8, 6, 4


Hence,


Mean score =


=


=


= 4.5


Therefore,


Mean score is 4.5.


(iv) Here,


As per the question,


We have to find the best performer among them.


Now,


We know that,


The best performer will be the one who will have the greatest average among all.


Thus,


Here,


We can observe that,


The best average among A, B, and C is of A that is 12.5


Hence,


We can say that,


A is the best performer among these three.
