A stock has a return that follows the normal distribution with a mean of 16% and a standard deviation of 7%. What is the probability that the stock will have a return between 16-7% and 16+2*7%? The one-, two-, and three-sigma probability of the normal distribution is 68%, 95%, and 99%. Enter a number with one decimal points. Answer the question in percentage terms, i.e., if the answer is 20%, enter 20.0.
