The following model predicts credit card acceptance (yes) as follows: p-value (0.001) Intercept BadReports (0.001) Income (<0.001) Here the response variable, CardAcceptance-1 if the card is accepted and 0 otherwise What is the effect of BadReport on Card Acceptance? Choose one from below: Coefficient 1.05 -1.36 0,026 As number of bad reports increases the probability of card acceptance decreases Bad reports has no effect on probability of card acceptance As number of bad reports decreases the probability of card acceptance decreases As the number of bad reports increases the probability of card acceptance increases
