Question

If the estimated slope coefficient  = - 2.50 and the standard error for the slope coefficient is 0.50, which of the following is true?
A)The t- statistic for the slope coefficient is - 5.0. 
B)The t- statistic for the slope coefficient is - 0.2. 
C)The P- value for the slope coefficient is - 0.2. 
D)The P- value for the slope coefficient is - 5.0.

Quizplus · Accepted Answer

The t-statistic for the slope coefficient is calculated by dividing the estimated slope coefficient by its standard error. Therefore, t = (-2.50)/0.50 = -5.0. Therefore, choice A is correct. The P-value cannot be negative and is not directly given, so choices C and D are incorrect.
