Answer to Problem 17HP

Equation of regression line is y=0.12x+0.33.

Equation of median-fit line is y=0.14x1.04.

Using regression line y=0.12(72)+0.339in.

Using median-fit line y=0.14(72)1.049in.

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.

  y=ax+b.Where,a=nxy(x)(y)nx2(x)2.b=yaxn.Where,  n=numberofobservations.

Calculation:

For 10 different people their Height(inches) and Head Height(inches) is given in below table.

    Height(in.)Head Height(in.)
    607.5
    63.57.8
    638
    648
    658.2
    688.5
    729
    71.59
    708.5

Using a graphing calculator ,the regression line is:

  y=0.12x+0.33.

Using a graphing calculator ,the median-fit line is:

  y=0.14x1.04.

Predict a person’s head length if his height 72 inches.

Using regression line y=0.12(72)+0.339in.

Using median-fit line y=0.14(72)1.049in.
