A researcher collected how many grams of fat people on a specific diet consumed at breakfast and at lunch.  The data for a sample of 8 people is shown in the table below.

 

xx 11.3 8.2 7.2 3.6 2.3 2.5 2.7 0.4
yy 13.7 10.7 10.2 7.2 6.3 6.5 6.1 4.1

 

xx = grams of fat in breakfast
yy = grams of fat in lunch

This data can be modeled by the equation ˆy=0.84x+4.07.y^=0.84x+4.07.
