2. At one university, the students are given z-scores at the end of each semester rather than the traditional GPAs. The mean and standard deviation of all students' cumulative GPAS, on which the z- scores are based, are 2.7 and .5, respectively. a. Translate each of the following z-scores to corresponding GPA: i. z=2.0 ii. Z=-1.0 b. Students with z-scores below -1.6 are put on probation. What is the corresponding probationary GPA? c. The president of the university wished to graduate the top 2.5% with summa cum laude honors. i. Where approximately should the limits be set in terms of z-scores? In terms of GPAS? ii. What assumptions if any did you make about the distribution of the GPAs of the university?

Two identically able agents are competing for a promotion. The promotion is awarded on the basis of output (whomever has the highest output, gets the promotion). Because there are only two workers competing for one prize, the losing prize=0 and the winning prize =P. The output for each agent is equal to his or her effort level times a productivity parameter (d). (i.e. Q2=dE1 , Q2=dE2). If the distribution of “relative luck” is uniform, the probability of winning the promotion for agent 1 will be a function of his effort (E1) and the effort level of Agent 2 (E2). The formula is given by...Prob(win)=0.5 + α(E1-E2), where α is a parameter that reflects uncertainty and errors in measurement. High measurement errors are associated with small values of α (think about this: if there are high measurement errors, then the level of an agent’s effort will have a smaller effect on his/her chances of winning). Using this information, please answer the following questions. Both workers have a…

1. Bothers John and Jason Rogers are trying to establish Illinois RiverHawk Floats to offer rafts for customers to float the Illinois River. 50 rafts are leased from a supplier for a monthly (30 days) cost of $415 per raft. The rafts are rented to customers for $25 per day. Customer demand follows a normal distribution, with a mean of 50 rafts and standard deviation of 8.5 rafts. (Make all demands integers in the model). If all 50 rafts are rented out, customers are referred to another outfitter who has a working relationship with the brothers. a. Set up the model and simulate a month (30 days) of operation to calculate the total monthly profit b. Replicate the simulation for 5 months (the expected float season) and determine the average total monthly profit. Note: this does not mean make 5 copies of the model. Run it 5 times, record and use the results appropriately.
