You are planning to save for retirement over the next 35 years. To do this, you will invest $900 per month in a stock account and $500 per month in a bond account. The return of the stock account is expected to be 11 percent, and the bond account will pay 7 percent. When you retire, you will combine your money into an account with a 8 percent return.

The Lake Placid Town Council decided to build a new community center to be: used for conventions, concerts, and oilier public events, but considerable controversy is appropriate size. Many influential citizens want a large center that would be a showcase for the area. But the mayor feels that if demand does not support such a center, the community will lose a large amount of money. To provide structure for the decision process, the council narrowed the building alternatives to three sizes: small, medium and large. Everybody agreed that the critical factor in choosing the best size is the number of people who will want to use the new facility. A regional planning consultant provided demand estimates under three responds to a situation in which tourism drops substantially, the base-case scenario coroner spends to a situation in which Lake Placid continues to attract visitors consultant has the best-case scenario corresponds to a substantial increase in tourism. The consultant has provided probability assessments of 0.10, 0.60, and 0.30 for the worst case, base-case, and best-case scenarios, respectively. The town council suggested using net cash flow over a 5-year planning horizontal as the criterion for deciding on the best size. The following projections of net cash flow (in thousands of dollars) for a 5-year planning horizon have been developed. All costs, in the consultant’s fee, have been included. What decision should Lake Placid make using the expected value approach? Construct risk profiles for the medium and large alternatives. Given the mayor s concern over the possibility of losing money and the result of part (a), which alternative would you recommend? Compute the expected value of perfect information. Do you think it would be worth trying to obtain additional information concerning which scenario is likely to occur? Suppose the probability of the worst-case scenario increases to 0.2, the probability of the base-case scenario decreases to 0.5, and the probability of the best-case scenario remains al 0.3. What effect, if any, would these changes have on the decision recommendation? The consultant has suggested that an expenditure of $150,000 on a promotional campaign over the planning horizon will effectively reduce the probability of the worst-case scenario to zero. If the campaign can be expected to also increase the probability of the best-case scenario to 0.4, is if a good investment?

EXPERT ANSWER a) Expected value of each case is given by: EVsmall = Probability of worst case*CF of worst case + Probability of basecase*CF of base case + Probability of best case*CF of best case EVsmall = 0.1*400 + 0.6*500+0.3*660= 40+300+198 =538 Similarly EVmedium = 0.1*(-250) + 0.6*650 + 0.3*800 = 605 EV large = …

As part of a study designed to compare hybrid and similarly equipped conventional vehicles, a group tested a variety of classes of hybrid and all-gas model cars and sport utility vehicles (SUVs). Suppose the following data show the miles-per-gallon rating obtained for two hybrid small cars, two hybrid midsize cars, two hybrid small SUVs, and two hybrid midsize SUVs; also shown are the miles per gallon obtained for eight similarly equipped conventional models.

Your job is to decrypt the intercepted message CONTNHRBDWMNACONVJC, which is believed to reveal the location of an important item. Your hint is that it is encrypted using a Caesar cipher, but we do not know the key. However, you have intercepted another message that may provide some useful information. 1. Since we know that the recipient of a ciphertext message must know the encryption key to decode the message, we were looking for a second message containing the key to our ciphertext, and we may have found it. We intercepted the encrypted message NEXYIYECEHTIRISNEHPK. Via social engineering, we believe the message sender likes to use route ciphers in a five-row by four-column grid. Past efforts lead us to believe she prefers to encrypt the message by writing the plaintext down the columns from right to left, and then spiraling counter-clockwise from the top-left corner. If the plaintext doesn’t fill the grid, she often uses X and Y to fill in the spaces. Reverse her process to reveal the plaintext! 2. If you correctly decrypted the message from step 1, you now have the encryption key for the original ciphertext, CQNTNHRBDWMNACONVJC. Use this key and your knowledge of Caesar ciphers to decrypt the first message and find the location of the secret object

EXPERT ANSWER Let us make the grid for the Route cipher and enter the key letters. The grid of 5 row x 4 column is incorrect as it produces this. As mentioned, the message is likely to be encrypted by writing down the plaintext down the columns from right to left and then spiraling counter …
