The results of a trial involving an experimental vaccine for children are shown below. Developed flu Did not develop flu Vaccine treatment 15 833 Placebo 127 292 a. State the relevant null and alternative hypotheses. b. Conduct the appropriate test and state a conclusion. Use a significance level of 0.01. O C. Ho: There is a relationship between treatment method and development of flu. HA: Treatment method is independent of flu development. O D. Ho: Treatment method and flu development have equal proportions. HA: Treatment method and flu development have non-equal proportions. b. Calculate the test statistic. * = (Round to three decimal places as needed.) Calculate the p-value. p-value = (Round to four decimal places as needed.) e%3D Determine a conclusion. Choose the correct answer below. O A. Do not reject the null hypothesis. There is sufficient evidence to conclude that treatment method and flu development are not independent. O B. Reject the null hypothesis. There is sufficient evidence to conclude that treatment method and flu development are not independent. OC. Do not reject the null hypothesis. There is insufficient evidence to conclude treatment method and flu development are not independent. O D. Reject the null hypothesis. There is insufficient evidence to conclude treatment method and flu development are not independent.
