Recall from Exercise 10.1.12 that the data fi le Roller
Coasters contains data (collected from www.rcdb.com) on the maximum speed
(miles per hour) and the maximum height (feet) for each of a sample of roller
coasters in the U.S.
a. State in words the appropriate null and alternative hypotheses
to test whether there is an association between maximum speed and maximum
height of such roller coasters.
 b. Describe how one might use everyday items (for example,
coins, dice, cards, etc.) to conduct a tactile simulation-based test of the
hypotheses. Be sure to clearly describe how the p-value will be computed from
the simulation.
