The width of the confidence interval estimate for the predicted value of y depends on all of these factors - the standard error of the estimate, the value of x for which the prediction is being made, and the sample size. A larger standard error of the estimate, a farther x value from the mean, and a smaller sample size will all result in a wider confidence interval.
