Identify the test statistic and the P-value, and then state the conclusion about the null hypothesis. The test statistic is (Round to two decimal places as needed.) dentify the P-value. The P-value is (Round to three decimal places as needed.) State the conclusion. Choose the correct answer below. OA. Reject the null hypothesis of dependence between whether the dog is incorrect and whether malaria is present. OB. Fail to reject the null hypothesis of independence between whether the dog is correct and whether malaria is present. OC. Reject the null hypothesis of independence between whether the dog is correct and whether malaria is present. OD. Fail to reject the null hypothesis of dependence between whether the dog is incorrect and whether malaria is present. b. Does rejection of the null hypothesis of independence imply that dogs are good at identifying malaria? OA. No. It is possible that the dogs are wrong significantly more than they are correct. OB. Yes. The data suggests dogs are excellent at identifying malaria because of their keen sense of smell. OC. Yes. They were correct much more than they were wrong, which is why the null hypothesis was rejected. OD. No. The data suggests dogs are not good at identifying malaria because of their keen sense of smell.

Question
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.
