Marc Duncan · Answer 1

The younger the person is the more can of soda they consume.

Based on the data, it is safe to say that younger people drink more soda. This can be inferred by finding the mean of each list of data.

To find the mean add up all the numbers and divide by the total number of people.

You will get the following values:

Ages 12 to 19: The mean is 10.04

Ages 20 to 39: The mean is 8.96
