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 linear equation relating Y to
x if we observe the following data for n=8 trees
Σ; α; = 192, Σ; yi = 258
–
Σ; 12; = 5280, Σ; wiyi = 6864
~ = 8. 25 + x
Οğ – 40. 5 + 9.06
Υ - 1. 29 + 2. 29x
Υ = 8. 40 + 1.32
