Project 1: Airline Overbooking

You are all packed an ready to go on a trip to New York City. After you check in at the ticket counter, the airline clerk announces that your flight has been overbooked. Passengers need to chek in immediately to determine whether they still have a seat.

Historically, airlines know that only a certain percentage of passengers who have made reservations on a particular flight will actually take that flight. Consequently, most airlines overbook= that is, they take more reservations than the capacity of the aircraft. Occasionally, however, more passengers will want to take a flight than the capacity of the plane, leading to one or more passengers being bumped and thus unable to take the flight for which they had reservations.

Airlines deal with bumped passengers in various ways. Some are given nothing, some are booked on later flights on other airlines, and some are given some kind of cash or airline ticket incentive. Consider the overbooking issue in light of the following COVID situation:

1. Fewer flights by airline from point A to point B.

2. Higher security, vaccine controls and mask mandates at airports.

3. Passenger’s fears to get infected with COVID-19.

4. Loss of billions of dollars in revenue by airlines during the pandemic.

Your time has been hired by an international airline for advise on the best possible strategy to resolve overbooking situations.

Build a mathematical model that examines the effects that different overbooking schemes have on the revenue received by an airline company in order to find an optimal overbooking strategy, that is, the number of people by which an airline should overbook a particular flight so that the company’s revenue is maximized. Ensure that your model reflects the issues above, and consider alternatives for handling bumped passengers. Additionally, write a short memorandum to the airline CEO summarizing your findings and analysis.

IMPORTANT NOTE; As I mentioned to you last time, start writing a survey of finding maximum and minimum of functions, including constraint minimizers (Lagrange multipliers) as in your calculus book. This should be your background material. Also you may use as a guide and source of materials, the book that I also mentioned by Mark M. Meerschaert ‘Mathematical Modeling” (electronic copy available at the UMN library). Another good approach is to go to the math library and search the shelf on optimizatioN.

# In the Segment Two Honors Project , you will use your statistical knowledge to m

In the Segment Two Honors Project , you will use your statistical knowledge to make an educated determination as to the effectiveness of the Power Pill.

The vitamin company that produces Power Pill claims that it increases hair growth while you sleep. In order to validate this claim, you must perform a series of statistical evaluations on the data and then make your final analysis.

First, the research participants must be divided into two groups—one receiving Power Pill and one receiving the placebo. Then the board of research expert doctors must be chosen, including a director, assistant director, quality control analyst, and correspondent.

Task 1 (of 3)

The first task of the Segment Two Honors Project is to select the Power Pill study participants’ groups and research board officers.

Part 1:

There are 40 volunteers for the research study on the Power Pill. Each subgroup of the study will contain 10 participants. Determine how many ways these participants can be selected and explain your method.

Part 2:

There are 15 research doctors participating in the study and the research board needs to be established with the offices of director, assistant director, quality control analyst, and correspondent. (Doctors can only hold one office on the research board.) Determine how many ways this research board can be chosen and explain your process.

Task 2 (of 3)

In Task 1, you selected the participants’ groups and assigned roles for the research board. For Task 2, you will now analyze the data collected from the groups.

The study participants were divided into four groups—two groups received the Power Pill (Group A and Group B) and two groups received a placebo (Group C and Group D). The effects of the Power Pill were measured. One group that received the Power Pill (Group A) and one group that received the placebo (Group C) were told of the anticipated effects of the Power Pill—accelerated hair growth—while the other two groups (Group B and Group D) were not provided with this information. All four groups were told to monitor and report any physical changes during the study.

Results were reported and participants were grouped as to either “Saw Results,” meaning that participants reported increased hair growth as part of physical changes during the study, or “No Results,” meaning that increased hair growth was not mentioned as part of physical changes during study.

Results are as follows:

6 in Group A saw results.

7 in Group B saw results.

5 in Group C saw results.

4 in Group D saw results.Part 1:

Create a two-way table for the data and find the probabilities for each group. Describe results in terms of the study.

Part 2:

What is the probability that a person saw results, given they received the Power Pill? What is the probability that a person saw results, given they received a placebo? Explain in terms of the study.

Part 3:

What is the probability that a person received the placebo, given that they did not see results? What is the probability that a person received the Power Pill, given that they did not see results? Explain in terms of the study.

Task 3 (of 3)

Part 1:

Based on your knowledge of fair decision making and probability concepts, should the Power Pill be produced and distributed? Explain your reasoning.

Part 2:

What effect (if any) did telling two groups about expected outcomes have on results? Use statistics to provide proof for your reasoning and explain.

Part 3:

Are there any flaws in the testing process? Should any of the steps or protocol be changed/avoided during round two of testing? Explain your reasoning.

# To be eligible for extra credit, you must submit your answers via this quiz by 5

To be eligible for extra credit, you must submit your answers via this quiz by 5:00pm (Pacific Time) on Wednesday, April 13th. If you get 80% or better, you will receive 4 extra credit points. Follow the below instructions for formatting your answers precisely.

If your answer is 1 or 0, you may simply input “1” or “0”. If your answer is between 0 and 1, you may input your answers as fractions or decimals.

If you input your answers as fractions, the fractions must be in simplest terms, with whole integers in the numerator and denominator. For example, the fraction 12/24 is not in lowest terms—it must be reduced to 1/2. When you enter your answer, enter the numerator, then a “/”, then the denominator. Do not include any spaces in your answer—e.g., write “1/2”, not “1 / 2″ or ” 1 /2″.

If you input your answers as decimals, you should round your answer to the 2nd significant digit. When you enter your answer, start with a 0 and a decimal point “0.”, then however many zeros are necessary, and finally the two significant digits. Again, do not include any spaces in your answer—e.g., if you get the answer 1/52=.0192307…, you should input the answer as “0.019”, not “.019″ or ” .019″ or “.0192” or “. 019” or “.02”. If the decimal has less than 2 significant digits, e.g. 2/5=.4, you can input the answer as “0.40” or “0.4”.
