I have already completed the project, but am not sure about some of my answers. This needs to be done perfectly, so I can check my answers. Also can you show your work so I understand how you got the answer you did and why my answers may be wrong.

Show steps for all problems. Attach the original Excel files, including the answer report and the sensitivity report for the LP models, and time series forecasting files.All airport passengers at the Capital City Airport must pass through a security screening area before proceeding to the boarding area. The airport has three screening stations available, and the facility managers must decide how many to open at any particular time. The average time for processing one passenger at each screening station is 0.5 minutes. On a Saturday morning, the arrival rate is 3passengers per minute. Assume that processing times at each screening station follow an exponential distribution and those arrivals following a Poisson distribution. Suppose two of the three screening stations are open on Saturday morning. Compute the following operating characteristics (show steps).a.The probability a passenger will have to wait.b.The average number of passengers that will be waiting for security screening.c.The average time a passenger waits in line.d.The average time required a passenger to pass through security screening.

Review the important themes within the sub questions of each bullet point. The sub questions are designed to get you thinking about some of the important issues. Your response should provide a succinct synthesis of the key themes in a way that articulates a clear point, position, or conclusion supported by research. You are designing a direct marketing campaign for an online clothing retailer. As part of your design, you quantify the expected response rates by ethnic group. Your definition of the term “ethnicity” follows that of the U.S. Census Bureau (e.g., Hispanic, Asian, African American, etc.). You want to test your campaign using 1,000 randomly selected households, but you want your sample to mimic the US population in terms of the proportion of different ethnicities (e.g., if Hispanics constitute about 12 percent of the US population, 12 percent of your sample should be Hispanic). Assess the appropriateness of using a simple random sample as the test’s sampling plan.Evaluate other potential sampling plans, and describe why such other sampling plans might be more or less appropriate than using a simple random sample. Support your discussion with relevant examples, research, and rationale. Your posting should be the equivalent of 1 to 2 single-spaced pages 500 words in length.
