Exercise 11-9 Algo A research analyst is examining a stock for possible inclusion in his client's portfolilo. Over a 19-year period, thelpample mean and the sample standard deviation of annual returns on the stock were 23% and 15%, respectively. The client wants to know if the risk, as measured by the standard deviation, differs from 19% (You may find it useful to reference the appropriate table: chisquare table or F table) a.
