Consider a binary response variable y and a predictor variable x that varies between 0 and 4 . The linear probability regression model is estimated as y^=1.15+0.57x a. Compute the estimated probability for x=2 and x=3. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) Note: Report the probability between 0 and 1 (not in \%). b. For what values of x is the estimated probability negative or greater than one? (Round your answers to 2 decimal places.)
