Question 19 Exercise 3.1

A cricketer scores the following runs in eight innings:

58, 76, 40, 35, 46, 45, 0, 100.

What is the mean score?

Answer:

Mean score = \frac{(Total\ runs\ scored\ by\ the\ cricketer\ in\ all\ innings)}{(Total\ number\ of\ innings\ played\ by\ the\ cricketer)}

Total runs scored by the cricketer in all innings = 58 + 76 + 40 + 35 + 46 + 45 + 0 + 100

= 400

Total number of innings = 8

Then,

Mean = \frac{400}{8}

= 50

∴Mean score of the cricketer is 50.
