Last ride Consider the roller coasters described in Exercise 30 again. The regression analysis gives the model Duration = 64.232 + 0.180 Drop.

 a) Explain what the slope of the line says about how long a roller coaster ride may last and the height of the coaster.

 b) A new roller coaster advertises an initial drop of 200 feet. How long would you predict the rides last?

 c) Another coaster with a 150-foot initial drop advertises a 2-minute ride. Is this longer or shorter than you’d expect? By how much? What’s that called?
