Consider a regression in which $b _ { 2 } = - 1.5$ and the standard error of this
coefficient equals 0.3. To determine whether $X _ { 2 }$ is a significant explanatory variable, you would
compute an observed t-value of - 5.0.

Question

Quizplus · Accepted Answer

The observed t-value is calculated as the coefficient divided by its standard error: $-1.5 / 0.3 = -5.0$.
