A market demand has 3 possible states namely GOOD, NORMAL and BAD for each period.At each period there are 2 possible decisions for the manager as do nothing/ make promotion. Thetransition matrix of states regarding for possible decisions are given as belowPof do nothingGOODNORMALBADGOOD0.40.2040.30.20.5NORMAL0.5BAD0.10.4Pof make promotionGOODNORMALBAD0.40.40.5GOOD0.2NORMAL040.1BAD0.30.40.3It is known that the income for each period when the state in GOOD, NORMAL and BAD are 10000,7000, 2000. Cost for do nothing is 0, and make promotion is 3000.a) Given at period 0 the state is NORMAL, estimate expected beneft obtain two periods when thesequence of decisions is do nothing, do nothingb) Given at period 0 the state is NORMAL, estimate expected beneft obtain two periods when thesequence of decisions is make promotion, make promotion

Let's consider a supermarket with three cash registers. The operation of the cash registers is checked daily, and if a register is found to be faulty, it is sent to the workshop for repairs. The probability of a working cash register breaking down is 1/5, and the probability of a cash register undergoing repair becoming operational is 3/5. The processes of breakdown and repair of cash registers are independent of each other. 1. (25 pts) Model this problem using a discrete time Markov chain. Present the transition probability matrix. 2. (15 pts) What is the long-run proportion of days when none of the cash registers are operational?
 Disease A was reported by local area hospitals in beginning in December 28, 1998.Initial symptoms were mainly bloody diarrhea, fever, weakness. Some later had fainting, hypotension.It was traced back to a potluck holiday party held in December 23 at a paper products sales company of 256 employees. All the employees attended that holiday party.One person died. The rest made full recoveries. No one who recovered from the illness showed any further symptoms. All data from the hospitals were compiled into the following chart: Date #cases Comment12/23/1998 0 Date of the holiday party.12/24/1998 0 12/25/1998 012/26/1998 012/27/1998 012/28/1998 212/29/1998 412/30/1998 812/31/1998 16 First patient in ICU for sepsis.1/01/1999 32 Second patient in ICU for sepsis.1/01/1999 30 The first patient expired in ICU.1/02/1999 26 The second patient transferred to regular ward.1/03/1999 18 The second patient discharged to home.1/04/1999 21/05/1999 01/06/1999 01/07/1999 0 21) What is the incubation period…

6. Interval estimation when o is unknown (the data “Alcohol" is provided) Consumption of alcoholic beverages by young women of drinking age has been increas- ing in the United Kingdom, the United States, and Europe (The Wall Street Journal, Feb- ruary 15, 2006). Data (annual consumption in liters) consistent with the findings reported in The Wall Street Journal article are shown for a sample of 20 European young women. 266 82 199 174 97 170 222 115 130 169 164 102 113 171 93 93 110 130 Assuming the population is roughly symmetric, construct a 95% confidence interval for the mean annual consumption of alcoholic beverages by European young women.
Top Cutz International Barbershop is a popular haircutting and styling salon . Four barbers work full-time and spend an average of 15 minutes on each customer. Customers arrive all day long at an average rate of 12 per hour. When they enter, they take a number to wait for the first available barber. Arrivals tend to follow the Poisson distribution, and service times are exponentially distributed. REQUIRED (c) What is the average time spent in the shop?
