What changes the variability of the coefficients?

The last three exercises have demonstrated how the variability in the slope coefficient can change based on changes to the population and the sample. Which of the following combinations increases the variability in the sampling distribution of the slope coefficient?

संभावित उत्तर

Bigger sample size, larger variability around the line, increased range of explanatory variable.

Bigger sample size, larger variability around the line, decreased range of explanatory variable.

Smaller sample size, smaller variability around the line, increased range of explanatory variable.

Smaller sample size, larger variability around the line, decreased range of explanatory variable.

Smaller sample size, smaller variability around the line, decreased range of explanatory variable.
