- This is a recurrence relations problem In Mayville, 90% of the existing dog licenses are reissued each year, and 1200 new licenses are issued. in 1995 there were 15,000 dog licenses issued. a. Write a difference equation and inital conditions describing the number of dog licenses Mayville will issue n years after 1995. b. How many dog licenses will Mayville issue in 2004? c. If the present trend continues, how many dog licenses can Mayville expect to issue after many years?Suppose that historically, 35% of applicants that are offered admittance to Texas Tech actually enroll, while the others take offers somewhere else. If Texas Tech will accept 9300 this coming year, what is the probability that less than 3250 will actually enroll? Use the normal approximation to the binomial. P(X < 3250)18. In a bank there are 2 checkouts, each with its own row of infinite size: checkout 1 for “fast” customers, with a time of 2 minutes, and checkout 2 for “slow” customers, with a time of 16.4 minutes, in both cases with exponential distribution. “Slow” and “fast” customers arrive according to an exponential function, with mean 8 and 20 minutes/customer, respectively. Some days, in particular, only 1 cashier comes to work who has to serve both lines according to the following cyclical sequence; 5 “fast” clients and 2 “slow” clients. The time to move between the boxes is 0.33 minutes. Simulate the process in ProModel for 80 hours and determine: The average number of customers waiting in each queue. The optimal service sequence to minimize waiting time, considering both types of customers.
- Suppose that historically, 36% of applicants that are offered admittance to Georgia Southern actually enroll, while the others take offers somewhere else. If Georgia Southern will accept 9150 this coming year, what is the probability that less than 3250 will actually enroll? Use the normal approximation to the binomial. P(X < 3250) =Data on the 4000 largest mutual funds shows which funds provided a high 5-year return and a high 10-year return. Of the 4000 mutualfunds surveyed, 3000 funds had a high 5-year return, 2000 had a high 10-yearreturn, and 1500 had both a high 5-year return and a high 10-year return Given that a mutual fund had a high 5-year return, what is theprobability of a mutual fund having a high 10-year return?The process for cleaning up waste in a nuclear reactor core room eliminates 85% of the waste present in the area.

Thepossible values at times T = 2 are thus 144, 108 and 81. The annually compounded interestrate is 5%. a) Write down the value of the money market account Mm at all states of the tree b) By using the martingale condition for Sm/Mm, find the risk-neutral probabilities withrespect to the money market numeraire Mm at each node of the tree.c) By using the the martingale condition for Z(m, 2)/Mm show thatZ(0, 2) = 6563 11.12 .d) Use (c) and an appropriate martingale condition to prove that the risk-neutral probability,with respect to the numeraire Z(m, 2) of the stock having value 120 at T = 1 is 44/65.Hence show that the risk-neutral probabilities of this state, with respect to the moneymarket account and the ZCB with maturity T = 2, differ by 2/195.

- According to scientists, the cockroach has had 300 million years to develop a resistance to destruction. In a study conducted by researchers, 6 comma 0006,000 roaches (the expected number in a roach-infested house) were released in the test kitchen. One week later, the kitchen was fumigated and 18 comma 10718,107 dead roaches were counted, a gain of 12 comma 10712,107 roaches for the 1-week period. Assume that none of the original roaches died during the 1-week period and that the standard deviation of x, the number of roaches produced per roach in a 1-week period, is 1.61.6. Use the number of roaches produced by the sample of 6 comma 0006,000 roaches to find a 9595% confidence interval for the mean number of roaches produced per week for each roach in a typical roach-infested house. Find a 95% confidence interval for the mean number of roaches produced per week for each roach in a typical roach-infested house.What is the general form of the solutions of a linear homogenous recurrence relation if its characteristic equation has the roots -1,-1,-1,2,2,5,5,7?A rodentologist investigating various aspects of the aging process wanted to see whether staying “lean and mean” that is, being under normal body weight would lengthen life span. She randomly assigned newborn rats from a highly inbred line to one of three diets: (1) unlimited access to food, (2) 90% of the amount of food that a rat of that size would normally eat, (3) 80% of the amount of food that a rat of that size would normally eat. She maintained the rats on the three diets throughout their lives and recorded their life spans (in years). Complete a Turkey's post HOC test to determine which one is significantly different
