Suppose a random sample of 200 20-year-old men is selected from a population and their heights and weights are recorded. A regression of weight on height yields \ Weight = −99.41 + 3.94(Height),R2 = 0.81,SER = 10.2
SE for beta_hat_0=(2.15), SE for beta_hat_1= (0.31)
where Weight is measured in pounds and Height is measured in inches. Two of your classmates differ in height by 2 inches. Construct a 99% confidence interval for the differences in weights.

Suppose that a random sample of 200 40-year old men is selected from a population and the annual income of each man is recorded. Suppose I am also able to obtain the annual income of each man's father when the father was 40. A regression of the former on the latter yields W? = 25 +0.5W where Wę and W are the annual income in thousands of dollars of man i and his father, respectively, both measured in 1980 dollars....
