Distribution of the residuals some statistical methods


Question: Distribution of the residuals. Some statistical methods require that the residuals from a regression line have a Normal distribution. The residuals for the nonexercise activity example are given in Exercise. Is their distribution close to Normal? Make a Normal quantile plot to find out.

Exercise: Find the sum of the residuals. Here are the 16 residuals for the NEA data rounded to two decimal places:
