In 1912, Over 800 passengers perished after the ocean liner Titanic collided with an iceberg and sank. The table below compares the survival frequencies of cabin and steerage passengers.
COMMODATIONS ON THE TITANIC

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