In a clinical trial of 2,150 subjects treated with a certain drug, 30 reported headaches. In a control group of 1,643 subjects given a placebo, 26 reported headaches. Denoting the proportion of headaches in the treatment group by \( p_t \) and denoting the proportion of headaches in the control (placebo) group by \( p_c \), the relative risk is \( p_t/p_c \). The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio, 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 \( \frac{p_t / (1 - p_t)}{p_c / (1 - p_c)} \). The relative risk is calculated to find the relative risk for the headache data.The relative risk = \(\Box\) (Round to three decimal places as needed.) Sure, here is a transcription suitable for an educational website:---In evaluating the effectiveness of a drug treatment, one measure used is the odds ratio. This is calculated by taking 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. This can be expressed as:\[\frac{p_t / (1 - p_t)}{p_c / (1 - p_c)}\]Where \( p_t \) is the probability of a headache in the treatment group, and \( p_c \) is the probability of a headache in the control group.The relative risk and odds ratios are important metrics commonly used in medicine and epidemiological studies. These measures help to determine the likelihood of an outcome occurring in a treatment group relative to a control group.**Task:** Find the relative risk and odds ratio for the headache data given. What do the results suggest about the risk of experiencing a headache from the drug treatment?--- This explanation provides the necessary context and details for understanding the importance and application of the odds ratio in medical studies.

Individual actions can play a large role in the overall health of our planet. A researcher interested in evaluating environment friendly behaviors evaluated how often people recycle (per month) based on whether they have an overall optimistic or an overall pessimistic attitude toward eco-friendly behaviors. The results from this hypothetical study are given in the table. Test whether or not recycling behaviors differed between groups using a .05 level of significance. State the value of the test statistics and the decision to retain or reject the null hypothesis. Compute effect size using eta- squared (n^2).

An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorption into the skin.Eight locations on the forearm were designated for ointment application.

Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.
