What proportion of points are within two standard deviations (2sd) and three
standard deviations (3sd) of the regression line?
We have data. How can we calculate sd of the regression and count the
number out of 2sd and 3sd? Can we use Minitab to do it? Thanks.

If you assume normal distribution and constant variance disturbance, is it
the same as asking the percentage within 2sd and 3sd for a normal
distribution. I think it is about 95% and 99%.
