Question
1. Which of the Independent variables are significant? Why? Explain. Use = 0.05 in ALL questions. Use only the p-value to explain your answers (No need to go to tables).
2. Test the overall significance of the model by conduction an F test.

1)here for level of significance is 0.05 ; therefore those variable will be significant where p vlaue is less than 0.05 level
hence from above table ' intercept ; x1.x2.x3.x6 all variables are significant due to reason their p values is less than 0.05 level
2)
from ANOVA table as p value is less than 0.05 level therefore overall model is significant
