Answer 2

$54.2

Explanation:

Average or mean of the data is the exact center point of the data. It basically shows the middle point of the data set so that one can estimate the nature of the data. The formula to calculate the mean is:

Mean = Sum of all observations / Number of observations.

Substituting the values gives:

Mean = (48.28+58.58+51.35+58.28+53.45+55.26)/6

Mean = 325.2/6

Mean = 54.2

So the average of the water bills is $54.2!!!
