Newspaper headlines at the time and traditional wisdom in the succeeding decades have held that women and children escaped a sunken ship in Female Male Total El greater proportion than men. Here's a table with the relevant data. Do you think that survival was independent of whether the person was male or Alive 379 322 701 female? Defend your conclusion. Dead 106 1363 1469 Total 485 1685 2170 Is there evidence of a signicant difference between the proportion of males and females who survived at the 0.01 level of signicance? What are the null and alternative hypotheses to test? L:- A. H0: Survival was independent of gender on the ship. HA: There is an association between survival and gender on the ship. " "- B. H0: There is an association between survival and gender on the ship. HA: Survival was independent of gender on the ship. Ej 1' C. H0: Survival was dependent on gender on the ship. HA: There is no association between survival and gender on the ship. ' ': D. H0: There is no associations between survival and gender on the ship. HA: Survival was dependent on gender on the ship. Are the conditions for inference satised? Yes, because the data are in counts, the data in groups are dependent on each other, and the groups are sufficiently large. "'- B. No, because the data are not in counts, the data in groups are independent, and there is at least one group that has less than 5 observations. Ej 1' C. Yes, because the data are counts, the data in groups are independent, and the groups have at least 5 observations. c: :- D. No, because the data are in counts, the data in the groups are dependent on each other, and the groups have at least 5 observations. Calculate the test statistic. X2 = D (Round to two decimal places as needed.) Determine the p-value and interpret its meaning. The p-value is D (Round to three decimal places as needed.) Interpret the pvalue. Choose the correct answer below. Fail to reject the null hypothesis and conclude there is weak evidence of an association between survival and gender on the ship. Both genders were equally likely to survive. Fail to reject the null hypothesis and conclude there is strong evidence of an association between survival and gender on the ship. Females were more likely to survive. Reject the null hypothesis and conclude there is weak evidence of an association between survival and gender on the ship. Both genders were equally likely to survive. Reject the null hypothesis and conclude there is strong evidence of an association between survival and gender on the ship. Females were more likely to survive
