Question: Paul has 10 chocolate chip cookies in his cookie jar and he wants to find out the average of chocolate chips in all of his cookies. He counted the number of chocolate chips and recorded them on a piece of paper: 5, 7, 6, 4, 8, 4, 6, 5, 8, 7. Find the average of chocolate chips per cookie?

Solution:

Step 1: find the sum of 5, 7, 6, 4, 8, 4, 6, 5, 8, and 7. Sum = 60

Step 2: Average = 60/10 = 6 chocolate chips/cookie (Hint: average = sum of all data/number of data)
