3. Two instructors announced that they "grade on the curve," that is, give a fixed percentage of each of the various letter grades to each of their classes. Their curves are as follows: Grade A Instructor A 8% Instructor B 10% B 12% 15% C 50% 50% D 20% 15% F 10% 10% a. What is the expected value of grade (using A-4, B=3, etc.) for each instructor? b. If a random student came to you and said that his object was to enroll in the class in which he could expect the higher grade point average, which instructor would you recommend?

Only typed answer and please don't use chatgpt otherwise I downvote the answer  Q = 12S1/2P-2. Q is number of newspapers sold and S is number of inches of news printed. The cost of reporting S units is $10S. The cost of printing one copy of the newspaper is $0.08, so the total cost of Q = $10S + .08Q. How many copies will be sold at the profit maximizing price when S = 100? Round (up) to the nearest newspaper.

A risk-neutral firm produces chemical products, and its objective is to maximize expected profit. There is a risk that there will be an accident during the production process, and dangerous chemical products will be released into the ocean, polluting the water. To reduce the risk of an accident, the firm can choose Low or High investment in safety. Low Investment in Safety_ Cost for firm= $0 Probability of an Accident = 80% Probability of No Accident =20% High Investment in Safety Cost for firm= $150 Probability of an Accident = 20% Probability of No Accident = 80% The Government wants to reduce the risk of an accident, but the Government cannot observe the fir m's investment in safety. Therefore there is a moral hazard problem. However, the Government can observe whether an accident occurred or not. So the government decides to create a fine (penalty): if an accident occurs, the firm must pay a fine F to the Government. If an accident does not occurs, then the firm does not have to…

efer to the following table showing the probability distribution of payoffs from an activity to answer the question below:    Units Payoff Probability 1 $30 10% 2 40 25% 3 60 30% 4 50 20% 5 10 15%   What is the expected value?

Question One. The ABC Book Company has a choice of publishing one of two books on the subject of Greek mythology. It expects the sales period for each to be extremely short, and it estimates profit probabilities as follows: Probability 0.2 0.3 0.3 0.2 Book A Profit Class Exercise $2,000 2,300 2,600 : 2,900 Probability 0.1 0.4 0.4 0.1 Book B Profit $1,500 1,700 1,900 2,100 Calculate the expected profit, standard deviation, and coefficient of variation for each of the two books. If you were asked which of the two to publish, what would be your advice?

Consider an investment that pays off $700 or $1,600 per $1,000 invested with equal probability. Suppose you have $1,000 but are willing to borrow to increase your expected return. What would happen to the expected value and standard deviation of the investment if you borrowed an additional $1,000 and invested a total of $2,000? What if you borrowed $2,000 to invest a total of $3,000? Instructions: Fill in the table below to answer the questions above. Enter your responses as whole numbers and enter percentage values as percentages not decimals (.e., 20% not 0.20). Enter a negative sign (-) to indicate a negative number if necessary. Invest $1,000 Invest $2,000 Invest $3,000 Expected Value Percent Increase Standard Deviation 1150 S 28 % $ 8 % $ Expected Return N/A Doubled Tripled : #

A wheel of fortune in a gambling casino has 54 different slots in which the wheel pointer can stop. Four of the 54 slots contain the number 9. For a 1 dollar bet on hitting a 9, if he or she succeeds, the gambler wins 10 dollars plus the return of the 1 dollar bet. What is the expected value of this gambling game? What is the meaning of the expected value result?

Givenu(x)=x0.5 Lottery A Probability 0.50 0.25 0.25 Outcome 64 16 0   For automatic grading, give all numerical answers to exactly two decimal places. Do not include currency signs 1) What is the expected value? (Give the answer as 36.00, not 36) 2) What is the expected utility? 3) What is the certainty equivalent? (Number only) 4) What is the risk premium? 5) Would this person rather receive 20 for sure than play Lottery A? (Answer should be Y or N for auto-grading to work) 6) (Harder) In many applications of expected utility, it is possible to lose money. The usual way of handling this is to interpret utility in terms of final wealth. Suppose it costs money to play this lottery. If starting wealth is 100, calculate the expected utility of playing lottery A if the price of playing is 15. Your answer should be to two decimal places. (Note: calculating the certainty equivalent of the lottery would be a little different than we've done in class. Squaring your EU result would give…
