Based on the residual plot, is the linear model
appropriate?
A statistics student is interested in the relationship
between the size of a pizza (the diameter measured in
inches) and its price. He collects a random sample of
pizzas from several local restaurants. He finds a linear
model to give the relationship between the size of the
pizza and the price. The equation of the line is û = -
8.1 + 1.91x, where y is the price and x is the diameter.
The residual plot is shown.
