A clinical trial is conducted to compare an experimental medication to placebo to reduce the symptoms of asthma. Participants are randomized to receive either the experimental medication or placebo. The primary outcome is self-reported reduction of symptoms. Among 120 participants who received the experimental medication, 76 reported a reduction of symptoms as compared to 43 participants of 120 assigned to placebo. We need to generate a 95% confidence interval for the difference in proportions of participants reporting a reduction of symptoms between the experimental and placebo groups. What is the 95% confidence interval for the odds ratio of participants reporting a reduction of symptoms in the experimental condition as compared to the and placebo condition.

Odds Ratio = 3.1, 95%CI: (1.6, 5.5)

Odds Ratio = 3.1, 95%CI: (1.8, 5.3)

Odds Ratio = 0.3, 95%CI: (-0.1, 0.7)

Odds Ratio = 0.3, 95%CI: (0.1, 0.5)
