Answer:
a. What is the average annual return?
average annual return (mean) = (-4.5% + 28.1% + 12.2% + 3.7%) / 4 = 9.875%
b. What is the variance of the stock's returns?
variance = [(-4.5% - 9.875%)² + (28.1% - 9.875%)² + (12.2% - 9.875%)²) + (3.7% - 9.875%)²] / 4 = (206.64 + 332.15 + 5.41 + 38.13) / 4 = 582.33 / 4 = 145.5825
c. What is the standard deviation of the stock's returns?
standard deviation = √145.5825 = 12.06%

Very few things have such a low price elasticity, and the fact that this is drug for treating cancer is the reason why that happens. Anyone that can purchase a drug that will keep you alive, will do so as long as you have enough money to do so. Another good with a very low price elasticity, but not 0, is gasoline with a 0.02 to 0.04, and gasoline is a basic necessity also.
The curve for a perfectly inelastic good is vertical. So any increase in taxes will be paid by the customers.
