- If you played the game in Exercise 1 many times, then you would expect your average payoff per game lo be about $ ____________.ABC enters into a contract to help DEF, a ramen restaurantto design a market strategy to compete with DEF. The contract spans twelve month. DEF will pay P80,000 at the beginning of each month. At the end of the contract, ABC either will give DEF a refund of P25,000 or will be entitled to an additional P15,000 bonus, depending on whether sales at DEF at year- end increased to a target level. At the inception of the contract , ABC estimates a 30% chance that it will not earn the bonus and calculates the contract price based on the expected value of future payments to be received. At the start of the fifth month, circumstances change and ABC revise the probability that it will earn the bonus to 80% What is the adjustment to the service revenue ?An electronics retailer is developing a model for insur-ance policies on new cell phone purchases. It estimates that 60% of customers never make a claim, 25% of cus-tomers require a small repair costing an average of $50, and 15% of customers request a full refund costing $200.What is the long-term average cost the retailer shouldexpect to pay to its customers per claim?
- The Majoring in Money study by Sallie Mae from December 2015 showed that most college students manage their credit cards in a reasonable way. It showed that almost two-thirds of students pay their credit card balance in full every month and 25% of students who own credit cards make partial payments that exceed the minimum amount due. You are curious to find out if credit card payment behavior of students has changed since 2015 and collect data from a random sample of 370 students. You find that 71 students are making partial payments on their credit cards that exceed the minimum amount due. Using α=0.01, complete parts a and b below.which is true about child and dependent care credit?Married couple to claim at least one spouse must work, be looking for work or be enrolled as full time student--or credit phases out when taxpayers AGI crosses certain threshold--or single taxpayer may claim credit for the care of certain disabled adult children who lived in household for more than 6 monthsUse answers to Q3b to determine a maximum and minimum expected value for the settlement
- A magazine distributor offers a first prize of$100,000, two second prizes of $40,000 each, and two third prizes of $10,000 each. A total of 2,000,000 entries are re-ceived in the contest. Find the expected payback if you submit one entry to the contest. If it would cost you $1 in time, paper,and stamps to enter, would it be worth it?A bank is considering offering a loan of $100,000 to a client. If the loan is not offered, then the bank invests the $100,000 receives a sure payoff from the investment of $200 (i.e., receives $100,200 at the end of the year). Prior to a decision of whether or not to offer the loan, the bank can run a credit analysis on the client that returns one of two possible predictions: (1) the client will default on the loan in which case the bank would lose $100,000, (2) the client will pay back the loan with interest in which case the bank receives a payoff of $6,000 (i.e., receives $106,000 at the end of the year). The probability that the credit analysis will return the first prediction (client defaults) is 1%. What is the EVPI?Federated South Insurance Company has developed a new screening program for selecting new sales agents. Their past experience indicates that 20% of the new agents hired fail to produce the minimum sales in their first year and are dismissed. Their expectation is that this new screening program will reduce the percentage of failed new agents to 15% or less. If that occurs, they would save $1,000,000 in recruiting and training costs each year. At the end of the first year they want to develop an evaluation to determine if the new program is successful. The following questions are an important part of their research design.A total of 20 new agents were selected.a. If this group performs at the same level as past groups, what is the probability 17 or more successfully meet their minimum sales goals in the first year?b. What is the probability 19 or more reach their minimum sales goals given performance at the same level?c. If the program has actually increased the probability of success to…

To disprove the claim, we checked with 10 different firms which used the software. These firms reported the following cost-saving yields (in percent) during the first year of their operations: {17.0, 19.2, 21.5, 18.6, 22.1, 14.9, 18.4, 20.1, 19.4, 18.9}. Do we have significant evidence to show that the software company’s claim of a minimum of 20 percent in cost savings was not valid? Test using α = 0.05. Compute a 95% confidence interval for the average cost-saving yield estimate.If the expected return on the market is 8% and the risk free rate is 4% and the expected return is 12%, what is the market risk premium ?
