Question 1 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.Now, Average number of bounces Shreyas makes per attempt = (𝑇𝑜𝑡𝑎𝑙 𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑏𝑜𝑢𝑛𝑐𝑒𝑠 𝑆ℎ𝑟𝑒𝑦𝑎𝑠 𝑚𝑎𝑘𝑒𝑠)/(𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑎𝑡𝑡𝑒𝑚𝑝𝑡𝑠) = (𝟔 + 𝟐 + 𝟗 + 𝟓 + 𝟒 + 𝟔 + 𝟑 + 𝟓)/𝟖 = 40/8 = 5 Thus, On an Average, Shreyas makes 5 bounces of the ball that Shreyas is able to make with his bat.
