WebThe standard deviation is 16.85 which seems far higher than the regression slope of 0.6991. But the regression slope is the average change in the waist size for a single unit shift of the weight. That means if a person is 10 units overweight than the other person, s/he will have 0.6991*10 or 6.99 unit more waist size.
