Consider a linear regression model where y represents the response variable and x, d₁, and d2 are the predictor variables. Both dy and da are dummy variables, each assuming values 1 or 0. A regression model with x, d₁, d2, and didy, where did is the interaction variable, is estimated as -1.340.82x 3.08d1 - 1.2002 0.58dydy.. a-1. Compute y for x 5,d₁ 1, and d₂0. Note: Round your answer to 2 decimal places. a-2. Compute y for x-5, dy 1, and dy 1. Note: Round your answer to 2 decimal places. b-1. Compute for x-5, d₁0, and d₂ - 0. Note: Round your answer to 2 decimal places.

Transcribed Image Text:Consider a linear regression model where y represents the response variable and x, d₁, and d2 are the predictor variables. Both di and
d₂ are dummy variables, each assuming values 1 or 0. A regression model with x, d₁, d2, and did, where did is the interaction
variable, is estimated as -1.34 + 0.82x + 3.08d₁1.20d2+ 0.58d1d2.
a-1. Compute y for x 5, d₁=1, and d₂ = 0.
Note: Round your answer to 2 decimal places.
a-2. Compute y for x-5, d = 1, and dy = 1.
Note: Round your answer to 2 decimal places.
b-1. Compute for x 5, d₁0, and d2 - 0.
Note: Round your answer to 2 decimal places.
Transcribed Image Text:b-1. Compute y for x=5, d₁= 0, and d₂ = 0.
Note: Round your answer to 2 decimal places.
b-2. Compute y for x=5, d₁= 0, and d₂ = 1.
