Men Women Boys girls Survived 332 318 29 27 Died 1360 104 35 18 Questions 1-5 refer to the sample data, which describes the fate of the passengers and crew aboard the Titanic when it sank on April 15, 1912. Assume that the data are a sample from a large population and we want to use a 0.05 significance level to test the claim that surviving is independent of whether the person is a man, woman, boy, girl. 4-Find the number of degrees of freedom. 5-Given that the p-value for the hypothesis test is 0.0000 when rounded to four decimal places, what do you conclude? what do the results indicate about the rule that women and children should be the first to be saved?
