Over the course of a clinical trial, 8,000 participants are given a trial drug for migraines. Suppose that the probability of the drug reducing migraines is 0.65.
- What is the probability that precisely 5250 participants will experience a reduction in migraines?
- What is the probability that at least 5250 participants will experience a reduction in migraines?
- What is the expected number of participants who will experience a reduction in migraines?
- What is the variance of the number of people who will experience migraines?
- What is the probability that no more than 3000 participants will not experience a reduction in migraines?

8. In a clinical trial of a drug used to help subjects stop smoking, 818 subjects were treated with 1 mg doses of the drug. That group consisted of 41 subjects who experienced nausea. The probability of nausea for subjects not receiving the treatment was 0.0096. Complete parts (a) through (c). Assuming that the drug has no effect, so that the probability of nausea was 0.0096, find the mean and standard deviation for the numbers of people in groups of...

3. Consider a Phase II clinical trial designed to investigate the effectiveness of a new drug to reduce symptoms of asthma in children. A total of n=10 participants are randomized to receive either the new drug or a placebo. Participants are asked to record the number of episodes of shortness of breath over a 1 week period following receipt of the assigned treatment. The data are shown below. Placebo: 7, 2, 10, 5, 12 New Drug: 3, 6, 4, 11,...

In a clinical trial of a drug intended to help people stop smoking, 127 subjects were treated with the drug for 11 weeks, and 18 subjects experienced abdominal pain. If someone claims that more than 8% of the drug's users experience abdominal pain, that claim is supported with a hypothesis test conducted with a 0.05 significance level. Using 0.17 as an alternative value of p, the power of the test is 0.95. Interpret this value of the power of the...
