Consider a linear regression model where y represents the response variable, x is a quantitative explanatory variable, and dis a dummy variable. The model is estimated as = 14.6 +4.5x - 3.4d. a. Interpret the dummy variable coefficient. Intercept shifts down by 3.4 units as d changes from 0 to 1. Slope shifts down by 3.4 units as d changes from 0 to 1. O Intercept shifts up by 3.4 units as d changes from 0 to 1. Slope shifts up by 3.4 units as d changes from 0 to 1. b. Compute y for x= 2 and d= 1. (Round your answer to 1 decimal place.) ў c. Compute y for x = 2 and d= 0. (Round your answer to 1 decimal place.)
