Question: Using 50 observations, the following regression output is obtained from estimating y = Î²0 + Î²1x +…

Using 50 observations, the following regression output is
obtained from estimating y = Î²₀ +
Î²₁x +
Î²₂d₁ +
Î²₃d₂ + Îµ.

a.	Compute for x = 312, d₁ = 1, and d₂ = 0; then compute for x = 312, d₁ = 0, and d₂ = 1. (Round your final answers to 2 decimal places.)

b-1.	Interpret d₁ and d₂. (You may select more than one answer. Single click the box with the question mark to produce a check mark for a correct answer and double click the box with the question mark to empty the box for a wrong answer.)

	When d₁ = 1, is 15.41 units greater than when d₁ = 0, holding everything else constant.
	When d₂ = 1, is 8.28 units greater than when d₂ = 0, holding everything else constant.
	When d₁ = 1, is 15.41 units less than when d₁ = 0, holding everything else constant.
	When d₂ = 1, is 8.28 units less when d₂ = 0, holding everything else constant.

b-2.

Are both dummy variables individually significant at the 5%
level?

	Yes, both dummy variables are individually significant at the 5% level.
	No, only the dummy variable d₂ is significant at 5% level.
	No, none of the dummy variables are individually significant at 5% level.
	No, only the dummy variable d₁ is significant at 5% level.
