Quizplus · Accepted Answer

The 95% confidence interval for a regression coefficient includes all the plausible values that the coefficient could take, based on the sample data. Choice A, (26, 148), suggests that for every unit increase in the Living Area variable, the dependent variable is expected to increase between 26 and 148 units, with 95% confidence. This interval does not include zero, indicating that the Living Area variable is statistically significantly associated with the dependent variable at the 95% confidence level. Other intervals either include zero (B and C), suggesting the possibility of no association, or are narrower (D), potentially indicating a more precise but not necessarily accurate estimate.
