Your textbook plots the estimated regression function produced by the probit regression of deny on P/I ratio The estimated probit regression function has a stretched "S" shape given that the coefficient on the P/I ratio is positive. Consider a probit regression function with a negative coefficient. The shape would
A) resemble an inverted "S" shape (for low values of X, the predicted probability of Y would approach 1)
B) not exist since probabilities cannot be negative
C) remain the "S" shape as with a positive slope coefficient
D) would have to be estimated with a logit function
Answer: A) resemble an inverted "S" shape (for low values of X, the predicted probability of Y would approach 1)

a. equals zero. b. is greater than the marginal cost of the test c. is lower than the marginal cost of an additional test d. equals the marginal cost of the test e. both a and b.
