When we make a prediction using multiple regression,we can apply a 95 percent confidence interval around the predicted dependent variable by multiplying:
A)1.96 times the standard error of the predictor.
B)1.96 times the standard error of the estimate.
C)2.58 times the standard error of the predictor.
D)2.58 times the standard error of the estimate.
E)1.96 times .95.

The 95% confidence interval around the predicted dependent variable can be calculated by multiplying 1.96 times the standard error of the estimate. The standard error of the estimate measures the variability of the predicted values around the true values and reflects the overall precision of the regression equation. Choice A and C refer to the standard error of the predictor, which is not relevant for calculating confidence intervals around the predicted dependent variable. Choice E is not a valid mathematical calculation.
