Calculate the odds ratio and interpret the estimated coefficient of Pclass2 with respect to the log-odds of survival and the odds of survival.
A. Odds ratio = exp(coefficient of Pclass2), interpretation: For every unit increase in Pclass2, the odds of survival decrease by the coefficient value.
B. Odds ratio = exp(coefficient of Pclass2), interpretation: For every unit increase in Pclass2, the odds of survival increase by the coefficient value.
C. Odds ratio = 1 / exp(coefficient of Pclass2), interpretation: For every unit increase in Pclass2, the odds of survival decrease by the coefficient value.
D. Odds ratio = 1 / exp(coefficient of Pclass2), interpretation: For every unit increase in Pclass2, the odds of survival increase by the coefficient value.
