![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, Συ-1761 , Σα 52729, Σν-286273, Συ- 122234
From these we calculate Sra

(Use these values in this and the following questions.)
Find the regression line y =

(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.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2f6b4d6e-a357-4c72-9272-e853a525214c%2F1bba3f47-16b7-4864-9b65-b680cfb929d4%2Fu1hllib_processed.jpeg&w=3840&q=75)
