Question

The personnel director for Electronics Associates developed the following estimated regression equation relating an employee's score on a job satisfaction test to length of service and wage rate.

ŷ = 14.4 − 8.69x_{1} + 13.52x_{2}

where

x_{1} |
= | length of service (years) |

x_{2} |
= | wage rate (dollars) |

y | = | job satisfaction test score (higher scores indicate greater job satisfaction). |

#1) Find the value of the test statistic. (Round your answer to two decimal places.) *F* =

Find the *p*-value. (Round your answer to three decimal places.)

#2)Did the estimated regression equation provide a good fit to the data? Explain. (Round your answers to two decimal places.)
*R*_{a}^{2} =

Since *R*^{2} =

#3) Find the value of the test statistic for ?_{2}. (Round your answer to two decimal places.) Find the *p*-value. (Round your answer to three decimal places.)
*p*-value =
