Answer to Question 1

There is no clear pattern. At first glance, there appears to be a weak, negative association between grams of fiber and the number of calories in the cereals. Yet, the five points at the bottom of the graph are outside the pattern, with extremely low numbers of calories. Additionally, the three points on the right of the scatterplot have an unusually high amount of fiber, making them outliers and influential points.

Answer to Question 2

It would be better for customers to have a negative residual from this model. A negative residual would indicate that the actual first class postal rate is lower than the model predicted it would be.
