(a)
To fit a straight line to the relationship of weight by year for Texas football players.
(a)
Answer to Problem 38RE
The line is
Explanation of Solution
It is given in the question the table which shows the average weight of the football team for the University of Texas for various years. Thus, to fit a straight line to the relationship of weight by year for Texas football players we will use Excel as we will first select the data in Excel and then go to the insert tab from where we will select the
Thus, the equation of the regression line is:
(b)
To find out in what year will the predicted weight of the Williams college team from exercise
(b)
Answer to Problem 38RE
It will be in the year
Explanation of Solution
It is given in the question the table which shows the average weight of the football team for the University of Texas for various years. And the regression line is as:
Thus, we will predict weight of the Williams college team from exercise
(c)
To explain do you believe this.
(c)
Answer to Problem 38RE
No, we do not believe.
Explanation of Solution
It is given in the question the table which shows the average weight of the football team for the University of Texas for various years. And the regression line is as:
Thus, we do not believe in this because both the predictions of weights require extrapolating.
