ompanies in the U.S. car rental market vary greatly in terms of the size of the fleet, the number of locations, and annual revenue. In 2011, Hertz had 320,000 cars in service and annual revenue of approximately $4.2 billion. Suppose the following data show the number of cars in service (1,000s) and the annual revenue ($ millions) for six smaller car rental companies.

Develop a scatter diagram with the number of cars in service as the independent variable.
A scatter diagram has 6 points plotted on it. The horizontal axis ranges from 0 to 14 and is labeled: Cars in Service (1,000s). The vertical axis ranges from 0 to 160 and is labeled: Annual Revenue ($ millions). The points are plotted from left to right in an upward, diagonal direction starting from the lower left corner of the diagram and are between 3 to 12 on…

a) Use the data to develop an estimated regression equation that could be used to estiamte the price for a bike given the weight.
b) Compare r^2. Did the estimate regression equation provide a good fit?
c) Predict the price for a bike that weighs 15 pounds?
d) Use the F test to determin whether the weight for a bike and the price are related at the 0.05 level of signifcance.
