Yes, the regression is significant.
Explanation (F-test method):
The calculated F-value ≈ 331.4
The Significance F ≈ 0 (very small p-value)
Since p < 0.05, we reject H0 and conclude that
the regression model is statistically significant overall .
Seniority (X1): p = 0.000 = significant
Age (X2): p = 0.00001 = significant
Experience (X3): p = 0.10216 = not significant
f at least one explanatory variable has p < 0.05 then the
regression model is significant
.
From the p-values:Seniority: p = 0.000 → significant
Age: p = 0.00001 → significant
Experience: p = 0.10216 → not significant
Answer: x3
