new drug is being proposed for the treatment of migraine headaches. The FDA will not approve the new drug if it does not show a statistically significant improvement as compared to a placebo. In an experiment 40 people who suffer from migraine headaches receive the new drug and 18 of them report an improvement in their migraine pain (group 2). Another 40 people were place in the placebo group (group 1). Of these 13 reported an improvement in their migraine pain. Help the FDA, by forming a conclusion based on the following supporting statistical evidence. Sample Data Sample X N Sample Proportion Placebo (group 1) 13 40 0.325 New Drug (group 2) 18 40 0.450 Difference = p1 - p2 95% Confidence Interval for Difference p1-p2: (-0.337, 0.087) P-value = 0.247 The estimated difference between the placebo group and the new drug treatment group is -0.125. A. True B. False
