Please answer the following question with the provided output:

Write the observed regression equation FOR MODEL 2 that predicts wages from length of service. How does this new model compare with the observed regression equation FOR MODEL 1?

MODEL 2 OUTPUT:

Simple linear regression results: Dependent Variable: Wages Independent Variable: LOS Wages = 43.898554 + 0.059247663 LOS Sample size: 58 R (correlation coefficient) = 0.30409097 R-sq = 0.092471321 Estimate of error standard deviation: 9.6517109 Parameter estimates:

Parameter Estimate Std. Err. Alternative DF T-Stat P-value
