Concept explainers
To find an equation for the regression line for each (men, women) and graph them. Compare and contrast men’s and women’s graph.
Answer to Problem 15HP
Equation for the regression linefor Men
Equation for the regression line for Women
The slop for women’s scores is steeper than men’s scores.
Explanation of Solution
Giveninformation: Below are the results of the W championships in2013.
Men | Score | Rank | Woman | Score |
S W | 98.00 | 1 | K C | 90.33 |
A H | 92.33 | 2 | E H | 90.00 |
M M | 91.33 | 3 | A G | 85.00 |
S L | 90.00 | 4 | T B | 82.00 |
G B | 84.66 | 5 | H T | 81.00 |
Formula used:
The equation for the regression line is given below.
Calculation:
For Men,
The graph for Men’s regression line is given below.
Where x- axis represents Rank and y −axis represents Scores.
For Women,
The graph for Women’s regression line is given below.
Where x- axis represents Rank and y −axis represents Scores.
So, it is clear from both graphs, the slop for women’s scores is steeper than men’s scores.
