Question: Last ride. Consider the roller coasters described in Exercise 16 again. The regression analysis gives the model Duration \(=91.033+0.242\) Drop.

  1. Explain what the slope of the line says about how long a roller coaster ride may last and the height of the coaster.
  2. A new roller coaster advertises an initial drop of 200 feet. How long would you predict the rides last?
  3. 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?
