Question 1 A bank with a branch located in a commercial district of a city has the business objective of developing an improved process for serving customers during the noon-to-1pm lunch period. Management decides to first study the waiting time in the current process. The waiting time is defined as the number of minutes that clapse from when the customer enters the queue until he/she reaches the teller's window. In addition, suppose that another branch, located in a residential area, is also concerned with improving the process of serving customers in the noon-to-1 pm lunch period and data were collected at random at these branches and recorded below: No. of Customers 1-5 6-10 11-15 16-20 21-25 Commercial District Branch Residential Area Branch (Waiting Time-Minutes) (Waiting Time-Minutes) 3 5 8 8 4 9 6 5 3 2 a) Which of the branches has a relatively better mean waiting time? b) Which shop can be surer of meeting the mean waiting time at the two branches? c) Assuming that the population variances from both banks are unequal, is there evidence of a difference in the mean waiting time between the two branches at 5% significant level?

If during the following year it is predicted that each comedy skit will generate 30 thousand and each musical number 20 thousand, find the maximum income for the year. A television program director must schedule comedy skits and musical numbers for prime-time variety shows. Each comedy skit requires 2 hours of rehearsal time, costs 3000, and brings in 20,000 from the shows sponsors. Each musical number requires 1 hour of rehearsal time, costs 6000, and generates 12,000. If 250 hours are available for rehearsal and 600,000 is budgeted for comedy and music, how many segments of each type should be produced to maximize income? Find the maximum income.
A road transport company has one reservation clerk on duty at a time. He handles information of bus schedules and makes reservations. Customers arrive at a rate of 8 per hour and the clerk can, on average service 12 customers per hour. Find(a) Average no. of customers waiting for the service of the clerk.(b) Average time a customer has to wait before being served.(c) The management is contemplating to install a computer for handling information and reservation. This is expected to reduce service time from 5 to 3minutes. The additional cost of the system works out to Rs 50 per day. If the cost of goodwill of having to wait is 12 paise per minute spent waiting, before being served, Should the company install the computer? Assume 8hours working day.
Faschip, Ltd., is a new African manufacturer of notebook computers. Their quality target is that 99.999% of the computers they produce will perform exactly as promised in the descriptive literature. In order to monitor their quality performance they include with each computer a large piece of paper that includes a direct—toll-free—phone number to the Senior Vice President of Manufacturing that can be used if the computer does not perform as promised. In the first year Faschip sells 1,000,000 computers.a. If they are achieving their quality target, what is the probability that they will receive fewer than 5 calls? If this occurs what would be a reasonable conclusion about their quality program? b. If they are achieving their quality target, what is the probability that they will receive more than 15 calls? If this occurs, what would be a reasonable conclusion about their quality program?

Hello, can you answer the problem in the photo I uploaded? thanks.
In May 2008, CNN reported that Sports Utility Vehicles (SUVs) are plunging toward the "endangered list". Due to soaring oil prices and environmental concerns, consumers are replacing gas-guzzling vehicles with fuel-efficientsmaller cars. As a result, there has been a big drop in the demand for new as well as used SUVs. A sales manager of a used car dealership for SUVs believes that it takes more than 90 days, on average, to sell an sUV. In order to test his claim, he samples 40 recently sold SUVs and find that it took an average of 95 days to sell an SUV. He believes that the population standard deviation is fairly stable at 20 days. Determine if the sales manager's claim is justifiable at 0.05
The service charge for repairs at an automobile service center is based on a standard time specified for each type of repair. The time specified for the replacement of the universal joint a driveshaft is one hour. To better serve the customers, the management would like to change the time specified in their service fee rates. The manager reviews such repairs and assumed that the workers are working faster than the standard time. The manager observed 30 of such repairs and gets an average repair time of 0.86 hours with a standard deviation of 0.32 hours. Test at the 1% level of significance the null hypothesis for the actual average time for this repair. Show the following steps. a. Formulation of the hypothesis and identifying the claimb. Determining what test to be usedc. Identifying the significance level and critical valued. Computation of the test statistice. Comparing the absolute value of the computed test statictic and critical value, decide whether null hypothesis is accepter…

Kolkmeyer Manufacturing Company is considering adding two machines to its manufacturing operation. This addition will bring the number of machines to nine. The president of Kolkmeyer asked for a study of the need to add a second employee to the repair operation. The arrival rate is 0.05 machines per hour for each machine, and the service rate for each individual assigned to the repair operation is 0.4 machines per hour. Mention the queuing model that can be implemented for the analysis (notation of Kendall) and why that model was chosen
A university engineering department has introduced a new software package called SOLVIT. To save money, the university’s purchasing department has negotiated a bargain price for a 4 user license that allows only 4 students to use SOLVIT at any one time. It is estimated that thsi should allow 90% of students to use the package when they need it. The student's union has asked for more licenses to be bought since engineering students report having to queue excessively to use SOLVIT. As a result the computer Centre monitors the use of the software. Their findings show that on average 20 students are logged on at peak times and 4 of these want to use SOLVIT. Was the purchasing department estimate correct? Answer this by yes or no and show your proof why you choose yes or no.
Suppose a group of consumers spend 30% of their disposable income on food, 20% on clothing, and 50% on rent. If over the course of a year the price of food rises 10%, the price of clothing drops 5% and rent rises 15%, what is the average price increase experienced by these consumers?
Glenn Howell, VP of personnel for the Standard Insurance Company, has developed a new training program that is entirely self-paced. New employees work various stages at their own pace; completion occurs when the material is learned. Howell’s program has been especially effective in speeding up the training process, as an employee’s salary during training is only 67 percent of that earned upon completion of the program. In the last several years, average completion time of the program was 44 days, and the standard deviation was 12 days. a) Find the probability an employee will finish the program in 33 to 42 days?b) What is the probability of finishing the program in fewer than 30 days?c) Fewer than 25 or more than 60 days?
