Concept explainers
(a)
To find out how many clusters of beetle larvae would you predict in a circular plot with
(a)
Answer to Problem 11E
We predict that there will be
Explanation of Solution
Now, as we know that in the previous exercise the computer output of this data is given. And also as we know the general regression equation be as:
And the estimate a and b are given in the column of the computer output “Coef”:
Thus, we will evaluate it for finding clusters of beetle larvae in a circular plot with
Thus, this means that we predict that there will be
(b)
To explain about how far do you expect the prediction in part (a) to be from the actual number of clusters of beetle larvae.
(b)
Answer to Problem 11E
The prediction will be off by
Explanation of Solution
It is given in the part (a) that:
We predict that there will be
Then as it is given in the computer output that,
Thus, the expected error made when making predictions is given by
