You are looking at buying a stock but want to understand its risk better. You do some calculations and figure that the expected return is 8% and the standard deviation is 12. The best case expectation is 32% and the worst case is (16%). What is the co-efficient of variation? Round to the nearest 1 decimal place and do not use a symbol. (e.g 1.8 would be a correct answer but 3 or .55 would be incorrect)
