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.)

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
