Concept explainers
(a)
To explain what are the variables and units in this regression.
(a)
Answer to Problem 16E
Length of initial drop in feet and duration of ride in seconds.
Explanation of Solution
It is given in the question that, people who responded to a discovery channel poll named the ten best roller coasters in the United States. In previous exercise it shows the length of the initial drop and the duration of the ride. A regression to predict duration from drop has
Thus, the variables of this context are length of initial drop in feet and duration of ride in seconds.
(b)
To explain what units does the slope have.
(b)
Answer to Problem 16E
Feet per second.
Explanation of Solution
It is given in the question that, people who responded to a discovery channel poll named the ten best roller coasters in the United States. In previous exercise it shows the length of the initial drop and the duration of the ride. A regression to predict duration from drop has
(c)
To explain do you think the slope would be positive or negative.
(c)
Answer to Problem 16E
The slope would be positive.
Explanation of Solution
It is given in the question that, people who responded to a discovery channel poll named the ten best roller coasters in the United States. In previous exercise it shows the length of the initial drop and the duration of the ride. A regression to predict duration from drop has
