The prediction interval accounts for the uncertainty in predicting a single response value, which includes the error in estimating the mean response (as in the confidence interval) plus the variability of the response around its mean. This is mathematically represented by adding "1" to the quantity under the radical sign in the formula, distinguishing it from the confidence interval formula.
