Calculate the test statistic: Fstat =

Identify the critical value: Fa =

State the conclusion for X1:

The variable X1 makes/does not make a significant contribution to the regression model because the test statistic is less than/greater than the critical value

Write the hypotheses for the contribution of variable X2.

H0: The response variable/Variable X1/Variable X2 does not significantly improve the model after variable X2/the response variable/variable X1 has been included.

H1: The response variable/Variable X1/Variable X2 significantly improves the model after variable X2/the response variable/variable X1 has been included

Calculate the test statistic: Fstat =

Identify the critical value: Fa =

tate the conclusion for X2:

The variable X2 makes/does not make a significant contribution to the regression model because the test statistic is less than/greater than the critical value

B. Compute the coefficients of partial? determination,r squared Y1.2 and r squaredY2.1?,and interpret their meaning.

The response variable/Variable X1/Variable X2 explains approximately r squared Y1.2 = ____ of the variation in The response variable/Variable X1/Variable X1 when the response variable/Variable X1/Variable X2 is held constant.

The response variable/Variable X1/Variable X2 explains approximately r squared Y2.1 = ____ of the variation in The response variable/Variable X1/Variable X1 when the response variable/Variable X1/Variable X2 is held constant.
