In a clinical trial of 2081 subjects treated with a certain drug, 21 reported headaches. In a control group of 1609 subjects given a placebo, 23 reported headaches. Denoting the proportion of headaches in the treatment group by p, and denoting the proportion of headaches in the control (placebo) group by p., the relative risk is p//p.. The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio, P: / (1 - PI ) which is the ratio of the odds in favor of a headache for the treatment group to the odds in favor of a headache for the control (placebo) group, found by evaluating Pc / (1 - Pc ) The relative risk and odds ratios are commonly used in medicine and epidemiological studies. Find the relative risk and odds ratio for the headache data. What do the results suggest about the risk of a headache from the drug treatment? Find the relative risk for the headache data. The relative risk = (Round to three decimal places as needed.) Find the odds ratio for the headache data. The odds ratio = (Round to three decimal places as needed.) What do the results suggest about the risk of a headache from the drug treatment? O A. The drug appears to pose a risk of headaches because the odds ratio is greater than 1.0. O B. The drug appears to pose a risk of headaches because p, is greater than p. O C. The drug does not appear to pose a risk of headaches because p, is slightly less than p. O D. The drug has no risk because the relative risk and odds ratio are almost equal.Five males with an X-linked genetic disorder have one child each. The X P(x) random variable x is the number of children among the five who inherit 0.026 the X-linked genetic disorder. Determine whether a probability distribution 0.149 is given. If a probability distribution is given, find its mean and standard 2 0.325 deviation. If a probability distribution is not given, identify the requirements 3 0.325 that are not satisfied. 4 0.149 5 0.026 Does the table show a probability distribution? Select all that apply. A. Yes, the table shows a probability distribution. OB. No, the random variable x's number values are not associated with probabilities. O C. No, the random variable x is categorical instead of numerical. OD. No, the sum of all the probabilities is not equal to 1. OE. No, not every probability is between 0 and 1 inclusive. Find the mean of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. H= child(ren) (Round to one decimal place as needed.) O B. The table does not show a probability distribution. Find the standard deviation of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. = child(ren) (Round to one decimal place as needed.) O B. The table does not show a probability distribution
