Question

The estimated regression equation for a model involving two independent variables and observations follows.

y = 33.2052 + 0.5821x1 + 0.5966x2

a. Interpret and in this estimated regression equation.

b1 = 

- Select your answer -

y changes by 0.5821 when x1 increases by 1 unit and x2 stays the same

y changes by 0.5821 when x2 increases by 1 unit and x1 stays the same

y changes by 0.5966 when x1 increases by 1 unit and x2 stays the same

y changes by 0.5966 when x2 increases by 1 unit and x1 stays the same

 

- Select your answer -

y changes by 0.5821 when x1 increases by 1 unit and x2 stays the same

y changes by 0.5821 when x2 increases by 1 unit and x1 stays the same

y changes by 0.5966 when x1 increases by 1 unit and x2 stays the same

y changes by 0.5966 when x2 increases by 1 unit and x1 stays the same

b. Estimate y when x1 = 180 and x2 = 310 (to 3 decimals).
