At a college basketball game, one lucky ticket holder will win an all-expenses-paid trip to the conference championship game. There are 4,000 ticket holders at the game. The organizers want to place chips, each labeled with the seat number of a ticket holder, in a bin and draw the winner from the bin. Unfortunately, the bin will hold only 400 chips. Which method assures both that the organizers can use the bin for the drawing and that each ticket holder will have a fair chance of winning? A. Place chips labeled with the seat numbers of each ticket holder into 10 groups based on age. Then randomly select one of the groups and place it in the bin. Randomly select the winner of the trip from the bin. B. Randomly assign the 4,000 ticket holders to 40 equal-sized groups. Then randomly select 4 of the groups and place their seat numbers in the bin. Randomly select the winner of the trip from the bin. C.

The manager of a small store decided to make half of his employees complete a mandatory training program. Among other things, the training program teaches employees to better serve the customers, be more proactive, appropriately greet customers, etc. After completion of the training program, the manager asks the group that did not receive the training program (non-training group 1) to work for a week (week 1) and then asks the group that received the training program (training group) to work the next week (week 2).

A marketing research group conducting a telephone survey must contact at least 150 wives and 120 husbands. It costs P100 to make a daytime call and (because of higher labor costs) P150 to make an evening call. On average, daytime calls reach wives 30% of the time, husbands 10% of the time, and neither of these 60% of the time, whereas evening calls reach wives 30% of the time, husbands 30% of the time, and neither of these 40% of the time. Staffing considerations mean that daytime calls must be less than or equal to half of the total calls made. How many should be interviewed at each period to minimize the cost of completing the survey? fomulate the LP Model; identify the decision variables used in the model; and determine the optimal solution using graphical method.

At their annual picnic, 18 students in the math & science departments at a local university decide to play a softball game. Twelve of the 18 students are math majors and 6 are science majors. To divide into two teams of 9, one of the professors put all the players' names into a hat and drew out 9 players to form one team, with the remaining 9 players forming theother team. The players were surprised when one team was made up entirely of math majors. Is it possible that the names weren't adequately mixed in the hat, or could this have happened by chance? Design and carry out a simulation using a calculator to help answer this question. a. What is the probability that there will be one team with all math majors?
Suppose I have 5 operators with different rates of productivity on the drill presses, stamping presses, and lathe in my facility (note that all 5 workers are trained to run any of the equipment). I need to assign these 5 workers to 2 drill presses, 2 stamping presses, and 1 lathe and I want to find the best assignment of workers. How many different ways can I assign the workers if Each type of machine is set up to do the same work (e.g., both stamping presses perform the same operation). Each type of machine is set up to do different work (e.g., both stamping presses perform different operations).

A snowboard manufacturer has three plants, one in the eastern United States, one in the western United States, and one in Canada. Production records show that the U.S. plants each produced 10,000 snowboards last month, while the Canadian plant produced 8000 boards. Of all the boards manufactured in Canada last month, 4% had a defect that caused the boards to delaminate prematurely. Records kept at the U.S. plants show that 3% of the boards manufactured in the eastern United States and 6% of the boards manufactured in the western United States had this defect as well. a) What proportion of the boards manufactured last month were defective? b) What is the probability that a snowboard is defective and was manufactured in Canada? c) Given that a snowboard is defective, what is the probability that it was manufactured in the United States?
