Solution Preview

The standard error of the estimate is a measure of the accuracy of predictions made with a regression line. The regression line seeks to minimize the sum of the squared errors of prediction. The square root of the average squared error of prediction is used as a measure of the accuracy of prediction. This measure is called the standard error of the estimate and is designated as ...
