Shreyas is playing with a bat and a ball — but not cricket. He counts the number of times he can bounce the ball on the bat before it falls to the ground. The data for 8 attempts is 6, 2, 9, 5, 4, 6, 3, 5. Calculate the average number of bounces of the ball that Shreyas is able to make with his bat.

Correct Answer

Given: Data: 6, 2, 9, 5, 4, 6, 3, 5

Formula: Average = Sum of values ÷ Number of values

Calculation: Sum = 6 + 2 + 9 + 5 + 4 + 6 + 3 + 5 = 40 Number of attempts = 8 Average = 40 ÷ 8 = 5

Answer: The average number of bounces is 5.

Explanation

The Arithmetic Mean is calculated as the sum of all values divided by the number of values. Average = (6 + 2 + 9 + 5 + 4 + 6 + 3 + 5) ÷ 8 = 40 ÷ 8 = 5.

Solution Steps

  1. Step 1: Add all the values: 6 + 2 + 9 + 5 + 4 + 6 + 3 + 5 = 40

  2. Step 2: Count the number of attempts: 8

  3. Step 3: Divide the sum by the number of values: 40 ÷ 8 = 5
