question 47

Short Answer

The linear regression equation G = a + bD is estimated using 24 observations on R and W. The least-squares estimate of b is -22.5, and the standard error of the estimate is 8.36. Perform a t-test for statistical significance of $\hat { b }$ at the 1% level of significance.
a. There are _____ degrees of freedom for the t-test.
b. The value of the t-statistic is _________. The critical t-value for the test is _________.
c. The parameter estimate
$\hat { b }$ _________ (is, is not) statistically significant at the 1% level.
