The mean height of American men in their early twenties is about 68.5 inches and the standard deviation is about 2.7 inches. The correlation between the heights of husbands and wives is about r=0.5. (a) What is the equation of the regression line of the husband's height (y) on the wife's height (x) in young couples?
