Question

If the standard error of the estimate for a regression model fitted to a large number of paired observations is 1.75, approximately 68% of the residuals would lie within ______

Answer 1

Approximately 68 percent of the residuals would lie within 1.75 units of the predicted values.

Step-by-step explanation:

For data having a distribution that is bell-shaped and symmetric, approximately 68 percent of the data is within one standard deviation of the mean. Therefore, if the standard error of the estimate for a regression model fitted to a large number of paired observations is 1.75, approximately 68 percent of the residuals would lie within 1.75 units of the predicted values.
