Solution:

i) Number of points scored by A in all games are -

Game 1 = 14

Game 2 = 16

Game 3 = 10

Game 4 = 10

Player A's number of points = \frac{14\ +\ 16\ +\ 10+10\ }{4}\ =\ \ \frac{50}{4}\ =\ 12.5

ii) To find the mean number of points per game for player C, we will divide the total points by 3 because player C played 3 games.

iii) Mean of player B's score = \frac{0\ +\ 8\ +\ 6\ +\ 4}{4}\ =\ \frac{18}{7}\ =\ 4.5

iv) The best performers will have the greatest average among all. Now we can observe that the average score of player A is 12.5 which is more than that of players B and C. Therefore, player A is the best performer among all three.
