Sound waves from a basketball. Refer to the American Journal of Physics (June 2010) study of sound waves in a spherical cavity, Exercise 11.31 (p. 629). You fit a straight-line model relating sound wave frequency (y) LO9 

to number of resonances (x) for n = 24 echoes resulting from striking a basketball with a metal rod.

a. Use the model to predict the sound wave frequency for the 10th resonance.

b. Form a 90% confidence interval for the prediction, part

a. Interpret the result.

c. Suppose you want to predict the sound wave frequency for the 30th resonance. What are the dangers in making this prediction with the fitted model?
