Question

Consider the estimated equation from your textbook

\widehat {\text { TestScore }}

=698.9 - 2.28

\times

STR, R² = 0.051, SER = 18.6 (10.4) (0.52)
The t-statistic for the slope is approximately

Quizplus · Accepted Answer

The t-statistic is calculated by dividing the coefficient by its standard error. Here, the slope coefficient is -2.28 and its standard error is 0.52. So, the t-statistic is -2.28 / 0.52 = -4.38.
