You wish to compare four treatments for effectiveness in preventing flu: (1) a flu vaccine, (2) 1 gram of vitamin C per day, (3) an Echinacea pill, (4) a turmeric curcumin complex pill, and (5) a placebo taken daily. (A placebo is a dummy pill which contains no active ingredient and should have no physical effect.)

In clinical experiments involving people, it is strongly recommended that a placebo be included among the treatments. Explain why.

What is an appropriate response variable?

Suppose that 1000 volunteer subjects are available for the study. Draw a diagram showing a

design of your experiment. Clearly indicate where randomization, replication and control are applied in the experiment.

2. A patient is resisting the idea of getting the annual flu vaccine, claiming to have already had the flu shot “sometime in the past couple decades”. a. Explain why it is important to receive an annual flu shot. What is the flu shot comprised of? Define and use the term “antigenic drift”. b. Continuing from above, what is “antigenic shift” and why and how can this occur in influenza viruses? How does this differ from antigenic drift, and why...

You are interested in comparing the effectiveness of zinc and vitamin C for preventing the common cold. Suppose that we randomly sampled 160 individuals who regularly take zinc and 204 individuals who regularly take vitamin C. Of the 160 zinc users sampled, 32 came down with the cold, and of the 204 vitamin C users sampled, 51 likewise came down with the cold. Test whether or not there is an equal proportion of cold sufferers across regular takers of zinc...

2.  The private marginal benefits for the flu vaccine is estimated to be MBp= 200-Q  where Q is the number of flu vaccines. The private marginal cost of producing the flu vaccine is MCp= 20. Because flu vaccines also reduce the probability that someone nearby receives the flu, there is a positive external benefit of MBe=100. No other externalities exist in the market.   a. Solve for the market equilibrium price and quantity for flu vaccines. Solve the socially optimal level of price...
