(a)

Use the data to develop an estimated regression equation thatcould be used to estimate the price for a bike given the weight.(Round your numerical values to the nearest integer).

Å· =

(b)

Compute

r².

(Round your answer to three decimal places.)

r²

=

Did the estimated regression equation provide a good fit?

The estimated regression equation provided a good fit, sincer² ≥ 0.55.The estimated regression equation didnot provide a good fit, since r² <0.55.     The estimated regressionequation provided a good fit, since r² <0.55.The estimated regression equation did not provide a good fit,since r² ≥ 0.55.

(c)

Predict the price (in dollars) for a bike that weighs 13 pounds.(Round your answer to the nearest dollar.)
