Question

A. Consider a drug that is used to help prevent blood clots in certain patients. In clinical​ trials, among 5824 patients treated with this​ drug,163 developed the adverse reaction of nausea. Use a 0.05 significance level to test the claim that 33​% of users develop nausea. Does nausea appear to be a problematic adverse​ reaction?

B. Assume that adults were randomly selected for a poll. They were asked if they​ "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human​ embryos." Of those​ polled, 486 were in​ favor, 395 were​ opposed, and 116 were unsure. A politician claims that people​ don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 116 subjects who said that they were​ unsure, and use a 0.05 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5 What does the result suggest about the​ politician's claim?

C. In a study of 815 randomly selected medical malpractice​ lawsuits, it was found that 520 of them were dropped or dismissed.
