Answer:
c. [tex]\hat{y}[/tex] = b₀ + b₁x₁ + b₂x₂
Step-by-step explanation:
The equation is given in option (a) is Simple Linear Regression Equation.
Option (b) & (d) is also not estimated regression equation.
The equation of estimated regression line is:
[tex]\hat{y} = b_{0} + b_{1}x_{1} + b_{2}x_{2}[/tex]
where, [tex]\hat{y}[/tex] is predicted value of y.
b₀ is intercept.
b₁ & b₂ is slope of regression line for x₁ & x₂ variable.
