Equation of regression line is
Equation of median-fit line is
Using regression line
Using median-fit line
Explanation of Solution
Given information: For 10 different people , measure their height and the length of their.
heads from chin to top. Use these data generate a linear regression equation and a median-fit equation.
Formula used:
The equation for the regression line is given below.
Calculation:
For 10 different people their Height(inches) and Head Height(inches) is given in below table.
Height(in.) | Head Height(in.) |
60 | 7.5 |
63.5 | 7.8 |
63 | 8 |
64 | 8 |
65 | 8.2 |
68 | 8.5 |
72 | 9 |
71.5 | 9 |
70 | 8.5 |
Using a graphing calculator ,the regression line is:
Using a graphing calculator ,the median-fit line is:
