Suppose a least-squares regression line is given by y=4.302x−3.293.
What is the mean value of the response variable if x=20?
u^y/20=
(Round to one decimal place as needed.)
The mean value of the response variable for x=20 is nothing but the value , regressor of y i.e takes at x=20
therefore answer is 4.302*20 - 3.293 = 82.747. = 82.7 (rounding off)
Therefore = 82.7
