This is the critical value. Compare the absolute value of each residual value in [L3] to 7.64. If the absolute value is greater than 7.64, then the (x, y) corresponding point is an outlier. In this case, none of the points is an outlier. To obtain estimates of y for various x-values: There are various ways to determine estimates for "y.

Critical value (z*) for a given confidence level. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate.
