A sample of n = 11 U. S. males, age 18-24 years, are measured for height and weight. Let x denote the height in inches, and let y denote
the weight in pounds. The summary data are
Σ = 761, Σ y = 1761, Σα? = 52729, Σy? = 286273, Σαμ = 122234
From these we calculate
Sex = 81.636, Syy = 4352.9, Szy = 394.8

Find the regression line y= bo + b1 a.
(Note: normally we would put a circumflex over the y: that is, "y-hat,"
but that notation is not available in the standard math editor.)
