To construct: a scatterplot for the given data and explain whether the assumption of linearity appear to be reasonable or not.

Solution Summary: The author explains that the assumptions of a linear relationship appear to be reasonable because the scatterplot does not contain curvatures. The mean is the sum of all values divided by the number of values.
