You are right, but only in a very strict, not-fun, manner :). Even if we had more data on different boats sinking, the model would not be very useful: We don't go with the Titanic anymore and plotted all icebergs. Still, if a cruise ship were to go down, I'd place a bet on ranking younger women of nobility traveling first class higher for survivability than old men with family traveling third class, wise predictor or no.
