Question

1. The regression analysis was rerun below dropping variables X4, X5, and X6. (50 observations)

Term	Coef	SE Coef	T-Value
Constant	-5.1	14.7	-0.35
X 1	12.44	2.32	5.36
X 3	6.41	1.70	3.76
X 7	0.0979	0.0510	1.92
X 9	-0.0263	0.0146	-1.80

Use the t test at the 0.05 level of significance to determine the significance of each independent variable.

• What is the value of the T Critical Point?               How many degrees of freedom?
• Would you eliminate any variable from the model?          

• If YES, which?
