Question

Becker and Kayla are members of the school chess team. They record the number of games they each play for 10 days. The data are shown below

Becker: 5,2,4,1,1,4,5,3,2,1
Kayla: 2,3,1,1,4,1,5,3,5,5

Based on the data, which estimate represents the mean of number of games chess team members play per day?

A.) 1
B.) 3
C.) 4
D.) 10

Answer 1

B.) 3

Explanation:

You add up all of the numbers from Beck which is 28. Now you do the same thing for Kayla, add up all the numbers from Kayla which equals 30. You add up their chess games 28 + 30 = 58 and then divide by the total number of days they played.. 20. 58/20 = 2.9. You round to the nearest tenth which would get you 3.

I hope this helps!! :)
