Use the following to answer questions 101-106:
A manager at a local bank analyzed the relationship between monthly salary and three independent variables: length of service (measured in months), gender ( 0 = female, 1 = male) and job type (0 = clerical, 1 = technical). The following ANOVA summarizes the regression results:

Reference: 14_06

graphic

The results for the variable gender show that

 

males average $222.78 more than females in monthly salary

 

females average $222.78 more than males in monthly salary

 

gender is not related to monthly salary

 

Gender and months of service are correlated.

Based on the hypothesis tests for the individual regression coefficients,

 

All the regression coefficients are not equal to zero.

 

"job" is the only significant variable in the model

 

Only months of service and gender are significantly related to monthly salary.

 

"service" is the only significant variable in the model

 

In the regression equation, what does the letter "b" represent?

 

Yintercept

 

Slope of the line

 

Any value of the independent variable that is selected
