Problem 42E
Last ride Consider the roller coasters (with the outlier removed) described in Exercise 30 again. The regression analysis gives the model 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 and a half-minute ride. Is this longer or shorter than you’d expect? By how much? What’s that called?
