You estimated a probit model with 2 independent variables X2 and X3. the estimated coefficients are b1=0.085 b2=0.62 and b3=-0.195. You are given the average of x2=1.5 and the average of x3=0.8. the effect of a unit increase in x2 on the probability that y=1 is Select one: O a. fall by 0.08 O b. an increase by 0.171 O c. an increase by 0.05 O d. an increase by 0.15You estimated a probit model with 2 independent variables X2 and X3. the estimated coefficients are b1=0.085 b2=0.62 and b3=-0.195.
