The following table lists results from an experiment designed to test the ability of dogs to use their extraordinary sense of smell to detect malaria in samples of children's socks (based on data presented at an annual meeting of the American Society of Tropical Medicine, by principal investigator Steve Lindsay). The accompanying information shows the hypotheses and TI-83/84 Plus calculator results for the experiment. Assume that the hypothesis test requirements are all satisfied. Complete parts (a) through (c) below. Malaria Was Present 123 52 Dog Was Correct Dog Was Wrong iClick the icon to view the hypotheses and the calculator output. Malaria Was Not Present 131 14 a. Identify the test statistic and the P-value, and then state the conclusion about the null hypothesis. The test statistic is 19.49 . (Round to two decimal places as needed.) Identify the P-value. The P-value is 0.000. (Round to three decimal places as needed.) State the conclusion. Choose the correct answer below. A. Reject the null hypothesis of dependence between whether the dog is incorrect and whether malaria is present. B. Fail to reject the null hypothesis of independence between whether the dog is correct and whether malaria is present. C. Reject the null hypothesis of independence between whether the dog is correct and whether malaria is present. O D. Fail to reject the null hypothesis of dependence between whether the dog is incorrect and whether malaria is present.
