Using these data, conduct the following analyses:(a) Plot and inspect the data. Summarize the dynamics with relevant ACF and PACF plots thataccount for the large drop in public drunkness arrests that occurs after June 1971. Discuss yourinitial models based on these diagnostics.(b) Fit an appropriate ARIMA model to the data from January 1966 to June 1971. Make sure youcheck the diagnostics to make sure there is no residual seasonal serial correlation.(c) Now include a permanent intervention variable that allows the constant in your model to changestarting in June 1971. Add this variable as a regressor in your ARIMA model and fit it to the fullsample. What do you conclude from this model. Hint: you can make the intervention variable using this intervene(d) Check and report the residual diagnostics for this model. What modifications need to be madeto the ARIMA specification after including the intervention?(e) Why is this procedure optimal? That is, why not just fit an ARIMA model to the full samplerather than use the part of the sample prior to the intervention like you did above?

Probability and Carnival Games Project AMDM Name___________________A local school is having a carnival to raise money for charity. Several groups are asked to create new carnival games that appeal to teenagers. The group with the best game will win a scholarship to the college of their choice. You will design a working scale model of the game. You are to create a report and a presentation addressing the following topics:Rules of the gamePrizes and how to earn the prizesExperimental (at least 100 trials) and theoretical probability of winning the gameExpected payoff for playerExpenses Profit for carnivalWhy the game should be selected for the carnivalRefer to the given rubric for the specifics needed for each topic.

MATH 178 Grossmont College Finding Cost Revenue and Profit Functions Report
report
The Problem: Marci Morgan is interested in buying and selling soybeans on the Chicago Board of Trade. She
remembers that they discussed concepts like price functions, revenue functions, cost functions, profit functions, marginal
cost, marginal profit, marginal revenue, etc. in her college calculus class. She would like to use some of these concepts
to help her make good business decisions. Her best guess is that the price function "p", in dollars, for selling "q" bushels
of soybeans is p(q) = -2q + 300. She has a supplier that will sell her the soybeans for $8 per bushel. She knows that
she will have fixed expenses (handling fees, commissions, taxes, etc.). She estimates that her fixed costs will be $80.
You should prepare two reports:
Report 1: A letter to Marci
Write a letter to Marci giving her the results that are of interest to her. What she really wants to know is the result: given
some price to be determined in the future, how does she decide how much to buy and what will be her expected profits.
You can present the results in the form of a formula or a graph or both. She does not want to read any mathematics,
but she wants to know that your results are based on mathematics. Give some idea of what you did, but explain your
procedure and results in plain English. Imagine that a student majoring in economics will grade your letter to Marci. You
may assume that the reader knows the meanings of the technical terms from economics.
Report 2: A Technical Report:
Write a report explaining the work that you did and what you learned. Assume that the reader is an "A" Calculus student
at some other school. You do not need to explain minor details of the calculations. However, your reader does not know
the meanings of the economic terms, so these must be explained. You must also explain your general procedures.
Your report should be completely independent of the project instructions. It should have an introduction that briefly states
the purpose of the work and the key results, followed by a body that is organized into sections for easy readability. Keep
in mind that you are writing about the problem, not your experience of solving it. ("The result is." rather than "First I
looked at." and "I found that the result was."). Assume that your technical report will be mailed to the reader with no
additional documentation. Your reader will study the report and then take a quiz written by your professor. This means
that the mathematics must be correct and well explained and the report must be readable and easy to study.
For a complete analysis of the problem you will need to include the following:
1. A revenue function, R(q), for selling q bushels at a price p(q)
2. A total cost function, C(q), for buying q bushels
3. A total profit function, P(q), for buying and selling q bushels
4. A graph of the three functions on the same coordinate system. (label your axes) What price per bushel should
she sell the beans to maximize her total profit? How many bushels would she need to sell? What price per
bushel?
5. A graph of the derivative functions R' (q), C' (q), and P'(q) on the same coordinate system. (label your axes).
Do the graphs of R' (q) and C' (q) intersect? If so, describe the significance of the point of intersection. Does
the graph of P' (q) intersect the q axis? If so, describe the significance of the point of intersection.
6. Compute the marginal profit for q = 200. Describe what this means.
7. If the supplier raises the price of beans to $9 per bushel how many bushels should she buy to maximize the total
profit?
8. The supplier changes the price so often that Laura decides to find a formula that will tell her what quantity, q, to buy at k dollars per bushel. Find this formula that will maximize her total profits.
