Question
In a controlled experiment, the height Y in feet of a tree and the amount of water x in
ounces received are measured. Find the least squares equation relating Y to x if we
observe the following data for n=8 trees
Σ; α; = 192, Σ; yi = 258
Σ; æ2; = 5280, Σæiyi
=
g=40.50+9.06x
=1.29+1.29x
g=8.25+x
g=8.40+1.3x
=
= 6864
