Homework Answers
The correct option is D) 34
Given,
Slope=b=3
Constant=a=4
The linear regression equation is
Y=a+bX=4+3*X
Y=4+3*X -------(1)
The predicted value of Y for X = 10 i.e. Value of Y when X=10
Put the value of X=10 in equation (1) we get
Y=4+3*10=34
The predicted value of Y for X = 10 is 34
