Consider the hummingbird data and information provided in Exercise IV. 10.
(a) Find the equation of the fitted regression line.
(b) Predict the wingbeat frequency for a hummingbird with 30 mm wings.
(c) Predict the mean wingbeat frequency for hummingbirds with 30 mm wings.
(d) Are the predictions of (b) and (c) interpolations or extrapolations? Briefly explain.
(e) Hummingbird B has wings that are 1mm longer than the wings of hummingbird A. How much faster or slower would you expect hummingbird B's wings to beat compared to A's?
