#### Solutions

Chapter 1, Problem 10P

a.

To determine

## Complete the table of winning pole vault heights.

Expert Solution

yearheight(m)19725.6419765.6419805.7819845.7519885.919925.8719965.9220005.920045.95

### Explanation of Solution

Calculation:

We have comlpleted the table with the help of example 2 .

yearheight(m)19725.6419765.6419805.7819845.7519885.919925.8719965.9220005.920045.95

Hence, the table completed.

b.

To determine

### Find the regression line for the data.

Expert Solution

H=0.027t47.969 ### Explanation of Solution

Calculation:

Consider the data given in table.

yearheight(m)19725.6419765.6419805.7819845.7519885.919925.8719965.9220005.920045.95

With the help of graphing calculator regression line is computed,

H=0.027t47.969

Now graph of regression line is, c.

To determine

### Plot the data and the regression line on the same axes.

Expert Solution

H=0.027t47.969 ### Explanation of Solution

Calculation:

With the help of graphing calculator regression line is computed,

H=0.027t47.969

Now graph both functions on same axis, d.

To determine

### Verify the regression line predict as the winning pole vault height for the 2008 Olympics.

Expert Solution

Prediction model gives higher value than actual height.

### Explanation of Solution

Calculation:

Put t=2008 in equation H=0.027t47.969 we get,

H=0.027t47.969H=0.027(2008)47.969H=6.247

The actual height was 5.96m

Hence, prediction model gives higher value than actual height.
