Question
The following ANOVA table was obtained when estimating a multiple linear regression model. Use Table 4.
ANOVA df SS MS F Significance F
Regression 2 22,356.81 11,178.41 0.0218
Residual 17 39,340.27 2,314.13
Total 19 61,697.08
a-1. How many explanatory variables were specified in the model?
Number of explanatory variables: ???
a-2. How many observations were used?
Number of observations: ???
b. Choose the hypotheses to determine whether the explanatory variables are jointly significant.
1)H0: 1 = 2 = 0; HA: At least one j < 0 ???
2)H0: 1 = 2 = 0; HA: At least one j 0 ???
3)H0: 1 = 2 = 0; HA: At least one j > 0 ???
c. Compute the value of the test statistic. (Round your answer to 2 decimal places.)
Test statistic: ???
Explanation / Answer
a) Number of explanatory variables: 2+1 = 3
How many observations were used = 19+1 = 20
b) H0: 1 = 2 = 0; HA: At least one j 0
Correct option is B
c) Test statistic = 11178.41/2314.13= 4.83
