Suppose we fit a logistic regression to the default data set to predict default yes customers where the coefficients are Coefficients balance $2\mathrm{.}7746990\mathrm{.}040451$ income student Yes $-0\mathrm{.}294785$ Which of the following statements are correct? $($may have multiple correct answers$)$ a$.$ Higher balance level means higher default risk since the coefficient is positive. Ob$.$ A student is more likely to default compared to a non$-$student. c$.$ Unit increase in balance will multiply the odd of default by $2,774699$ d$.$ As income increases the default risk decreases.
