Question: 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).
- Devel0p a scatter diagram for these data with baggage capacity rating as the independent variable.
- What does the scatter diagram developed in part (a) indicate about the relationship be« tween baggage capacity and price?
- Draw a straight line through the data to approximate a linear relationship between baggage capacity and price.
- Use the least squares method to develop the estimated regression equation.
- Provide an interpretation for the slope of the estimated regression equation.
- Predict the price for a boat with a baggage capacity rating of 3.
