Question
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.
ANOVA
| Source of Variation | df | Sum of Squares | Mean Square | F |
|---|---|---|---|---|
| Regression | 3 | 1,004,346.771 | 334,782.257 | 5.96 |
| Residual | 26 | 1,461,134.596 | 56,197.48445 | |
| Total | 29 | 2,465,481.367 |
| Coefficients | Standard Error | t-Stat | p-value | |
|---|---|---|---|---|
| Intercept | 784.92 | 322.25 | 2.44 | 0.02 |
| Service | 9.19 | 3.20 | 2.87 | 0.01 |
| Gender | 222.78 | 89.00 | 2.50 | 0.02 |
| Job | −28.21 | 89.61 | −0.31 | 0.76 |
The level of significance is 0.05. Based on the hypothesis tests for the individual regression coefficients, ________.
Multiple Choice
-
all the regression coefficients are not equal to zero
-
"Job" is the only significant variable in the model
