Suppose that a random sample of 198 twenty-year-old men is selected from a population and that their heights and weights are recorded. A regression of weight on height yields
Weight=(98.4159) + 3.9006Height, R2 = 0.802, SER= 10.0980
(2.1285)(0.3069)
where Weight is measured in pounds and Height is measured in inches.
