Technological advances helped make inflatable paddle craft suitable for backcountry use. These blow-up rubber boats, which can be rolled into a bundle not much bigger than a golf bag, are large enough to accommodate one or two paddlers and their camping gear. Canoe & Kayak magazine tested boats from nine manufacturers to determine how they would perform on a three-day wilderness paddling trip. One of the criteria in their evaluation was the baggage capacity of the boat, evaluated using a 4-point rating scale from 1 (lowest rating) to 4 (highest rating). The following data show the baggage capacity rating and the price of the boat (Canoe & Kayak, March 2003).

a) Which of the following scatter diagrams accurately represents the data?

b) Compute b1 and b0
c) Complete the estimated regression equation (to 2 decimals).
y = + X
A one point increase in the baggage capacity rating will increase the price by approximately.
d) Predict the price for a boat with a baggage capacity rating of 3.
