You can carry out the work for fixed or random predictors (slightly different setups in the calculations). Play games and win prizes! Laden... Unless the histogram of residuals evidences a strong departure from Normality, I would not be concerned with non-Normal errors.

However, you'd either have to write the code yourself to use in Excel or get some software that has some real statistics capability (R (or S), SAS, Minitab (little work required Are there any general rules for how one does this replacement to minimize the chance of gross overestimation? How To Calculate Standard Error Of Slope Coefficient In Excel How do **I solve this physics problem?**

I will take your advice and see how the bootstrap technique, in the absence of error data, compares with a Monte Carlo simulation *with* error data. For example, select (≠ 0) and then press ENTER.

But that's the meaning of standard error of the slope; when taking data, you might just as well have measured (3,7) instead of (2,9).
