A contingency table is constructed that shows the number of passengers who survived/died according to whether they were male, female, boy or girl.

The null hypothesis is as follows:

The survival of the passenger is independent of whether he/she is a man, woman, boy or girl.

The alternative hypothesis is as follows:

The survival of the passenger is not independent of whether he/she is a man, woman, boy or girl.

The p-value is equal to 0.000.

The level of significance is equal to 0.05.

Since the p-value is less than 0.05, the null hypothesis is rejected.

There is enough evidence to conclude that thesurvival of the passenger is not independent of whether he/she is a man, woman, boy or girl.

It is a rule that in times of calamities, the women and the children are saved first.

Here, since the survival of the passenger depends upon his/her age group and gender, it can be said that the above rule was followed at the time when the Titanic sank.

This also results in a large number of casualties for the male gender who are adults.
