Both a confidence interval and a prediction interval use the standard error of estimate to calculate the bounds of the interval. However, they differ in their interpretations - a confidence interval provides a range of values in which the true population mean is likely to fall, while a prediction interval provides a range of values in which individual future observations are likely to fall. The formulas used and the width of the intervals may also differ between the two.
