Which of the following does NOT affect the standard error of the regression slope?
A) Spread around the line: se
B) Spread of x values: sx
C) Sample size: n
D) Critical value: t*
E) All of these affect the standard error.

Quizplus · Accepted Answer

The standard error of the regression slope is only affected by the spread around the line (se), the spread of x values (sx), and the sample size (n). The critical value (t*) is used to calculate the confidence interval for the slope, but it does not directly affect the standard error. Therefore, the correct answer is D.
