Using the .05 level of signiﬁcance, test the null hypothesis that survival rates are independent of the passengers’ accommodations (cabin or steerage).
Assuming a signiﬁcant c2, estimate the strength of the relationship.
To more fully appreciate the importance of this relationship, calculate an odds ratio to determine how much more likely a cabin passenger is to have survived than a steerage passenger.
