4-86.

A human resources manager recorded the experience and hourly wage for a sample of 10 technology workers.

Experience (years) | | | | | | | | |||
---|---|---|---|---|---|---|---|---|---|---|

Hourly Wage ($) |

Sketch a scatterplot showing the association between the wage and the years of experience. Describe the association.

Create a scatterplot with the

-axis labeled "Experience (years)" and the*y*-axis labeled "Hourly Wage ($)."

Sketch the residual plot. Is a linear model appropriate?

What is the correlation coefficient? What does it tell you?

Remember that the correlation coefficient,

, is a measure of how much or how little the data is scattered around the LSRL.
