A researcher is trying to develop a treatment for a new viral disease. He recruits 100 patients who have the disease and randomly assigns them to two groups (50 patients in each group). One group gets the new anti-viral drug and the other group gets an inactive placebo. He then monitors the severity of their condition for the next week by counting the number symptoms they display each day and creates a total symptom summary score.

A scientist has developed a new anti-viral drug to treat people with the coronavirus. He believes that this drug will kill the virus and cure people of this disease. In order to test this drug, he gives 10 people with the coronavirus a previously known anti-viral drug for 2 weeks, and monitors their symptoms to see if they get better. He gives another 10 people with the coronavirus a placebo for 2 weeks, and monitors their symptoms to see if they get better. This experiment is missing the ____ group.

A researcher wishes to test the effectiveness of flu vaccination. 150 people are vaccinated, 180 people are vaccinated with a placebo, and 100 people are not vaccinated. The number in each group who later caught the flu was recorded. The results are shown below. Vaccinated Placebo control Caught the flu 8 19 21 Vaccinated Placebo 142 161 79 Use a 0.05 significance level to test the claim that the proportion of people catching the fly is the same in all 3 groups.

Suppose a student carrying a flu virus returns to an isolated college of 1000 students. If it is assumed that the rate at which the virus spreads is proportional not only to the number x of infected students but also to the number of students not infected, determine the number of infected students after 6 days if 50 students are infected after day 4. DO NOT ROUND K ON THIS PROBLEM. Assume that no one else has the flu when the student returns and no one leaves or arrives on campus during this time.
