A new sample of size 8 was collected of father adult weight (x) and newborn son weight (y) (in pounds) and a positive linear association was found to be significant. From this data, it was calculated  ?x = 1491,  ?x² =282475,  ?y= 65.2,  ?y² = 538.5,  ?xy = 12330.1

Showing your work, find the correlation coefficient, a linear model, and use the model to estimate a newborn son's weight if a father's weight is 220 pounds.
