Coasters again.
Given Exercise examined the association between the Duration of a roller coaster ride and the height of its initial Drop, reporting that Write a sentence (in context, of course) summarizing what the R2 says about this regression
Exercise:
Roller coaster. People who responded to a July 2004 Discovery Channel poll named the 10 best roller coasters in the United States. A table in the last chapter's exercises shows the length of the initial drop (in feet) and the duration of the ride (in seconds). A regression to predict Duration from Drop has R2 = 12.4%.
a) What are the variables and units in this regression?
b) What units does the slope have?
c) Do you think the slope is positive or negative? Explain.
