Calculate the 95% confidence intervals for the proportion of children surviving, and the proportion of non-crew adult passengers surviving. We want to use the given data to make inferences about the general population of all large boat crashes, so the data set should be treated as a random sample for this purpose. Part 2 The 95% confidence interval for survival rate amongst non-crew adults runs from enter your response here% to enter your response here%. (Round to one decimal place as needed. Use ascending order.) Part 3 The 95% confidence interval for survival rate amongst children runs from enter your response here% to enter your response here%. (Round to one decimal place as needed. Use ascending order.) Part 4 Test the alternative hypothesis that the proportion of children surviving does not equal 35%, and next, test the alternative hypothesis that the proportion of non-crew adult passengers surviving does not equal 35%. Again, the data set should be treated as a random sample for this purpose. Part 5 Based on the StatCrunch output, what do we conclude? A. We cannot reject either of the null hypotheses. B. We reject the null hypothesis that the non-crew adult survival rate is equal to 0.35, but cannot reject the null hypothesis that the child survival rate is equal to 0.35. C. We reject both null hypotheses. D. We reject the null hypothesis that the child survival rate is equal to 0.35, but cannot reject the null hypothesis that the non-crew adult survival rate is equal to 0.35.
