Value at Risk. Financial analysts commonly use an approach called value at reisk to compare the risk of stocks or portfolios. The analyst tries to estimate a low percentile (such as the 5th or 10th percentile) of the forecasted range of possible returns for a given stock or portfolio and that percentile is used as a rough measure of the worst-case senario for that investment. Suppose an analyst is trying to compare two investments: Investment A has a forecasted average return of $10 million with a standard deviation of $3 million, and Investment B has a forecasted average return of $12 million with a standard deviation of $5 million. The analyst wants to avoid risk and invest in the one that has a larger 5 percentile for the return distribution. Which investment should he/she make

Areal estate agent is considering changing her cell phone plan. there are three plans to choose from, all of which involve a monthly service charge of $20. plan a has a cost of $.42 a minute for daytime calls and $.17 a minute for evening calls. plan b has a charge of $.52 a minute for daytime calls and $.15 a minute for evening calls. plan c has a flat rate of $80 with 275 minutes of calls allowed per month and a charge of $.38 per minute beyond that, day or evening. a. determine the total charge under each plan for this case: 150 minutes of day calls and 70 minutes of evening calls in a month. (do not round intermediate calculations. round your answer to 2 decimal places. omit the "$" sign in your response.)c. if the agent will use the service for daytime calls, over what range of call minutes will each plan be optimal? (round each answer to the nearest whole number. include the indifference point itself in each answer.)d. suppose that the agent expects both daytime and evening calls. at what point (i. e., percentage of total call minutes used for daytime calls) would she be indifferent between plans a and b?
