I need to do a report and I need to write the methods and results on the hypothesis tests for the full set and the 7 waves, I am uploading the power point presentation, the excel data and draft of our reseaqrch paper.

This is STAT 101 PLS SEND IT AS A MICROSOFT WORD .
Visit one of the polling sites listed and choose one poll to analyze
1- Go to one of these sites: Quinnipiac PollLinks to an external site., Marist PollLinks to an external site., 538Links to an external site. (political polling), Washington Post Poll,Links to an external site. Fox News PollLinks to an external site.. (Note: the first two, Quinnipiac and Marist, are academically based well respected polling centers. The last two are journalistic and are known to have a particular point of view (bias)Links to an external site., the Washington Post leans ‘left’ and Fox New is decidedly ‘right’, politically speaking.
Spend a little time clicking on the different topics and polls – those that you find interesting – look at the dates, questions, answers and answer patterns (%s) and other information (N, Margin of error!)…
2- After you have looked at many questions, choose one poll and one question (& its answers) to use for this discussion.
Ensure that it is a poll that is recent – not old!
You’ll need the percent for one of the responses to the question and the N. Look for the N in the ‘fine print’ – if you chose a legitimate poll, it should have the N and their margin of error calculation available near the poll findings.
3- Then, for the question you chose, post the following – using the question topic as your post subject
1- the link to the web page where you got the data so we can go look at it
2-your own calculation of the margin of error (for one of the answer categories) and whether or not your margin of error matches the one they stated, and
3- a brief interpretation of the results – use the sentence structure we use in our class work.
I uploaded an example for this question. please do it correctly and as the example provided!!!!! Thanks

Message: Social responsibility is a framework of ethics in which an individual collaborates and works with other organizations and individuals for the betterment of the community. There are numerous ways in which an organization can exhibit social responsibility; for instance, by promoting volunteerism, facilitating donations, employing ethical employment practices, and implementing environmental improvements. It introduces the subjective obligation that entails maintaining a delicate equilibrium between one’s ecosystem and the economy, as well as the potential compromises that may be made between economic progress and societal and environmental wellbeing. This transcends business organizations and affects all individuals whose actions influence the environment.
Solve the following questions using Excel QM. (2×4 = 8 marks)
Helping others through blood donation is a form of social solidarity or social responsibility. The blood donors cite a sense of social responsibility as their reason for donating blood, and as a result, the communities value and reward this activity. The following table shows the number of blood donors in a university from 2011–2023. Develop a 3-year moving average forecast and obtain the related statistical measures using excel QM.
University X has a unique on-campus dispensary that provides medical care. On a typical working day, patients arrive at the dispensary at an average rate of 2 patients per hour. There is one single nurse at the dispensary, and the average time required to give a consultation is 12 minutes.
Assume that you are a statistical consultant and want to provide a volunteer consultation to a start-up company as a social responsibility consultation. The company is planning to purchase a uniform outfit for their employees, and they obtained the following quantity discount table with three discount options:
To help needy people through charity is a form of social responsibility. The act of doing charity to help others is recognized and rewarded by all communities of the society. The following table shows the amount collected through charity and the amount spent on social development (in million dollars) in the last 8 years. Find the correlation and coefficient of determination for the given data and obtain the related statistical measures using excel QM.

Solution:
It is assumed that the service times can be described by the exponential distribution, and the arrival process by a Poisson distribution. You are requested to find:
The average time in line,
The average number of patients in line,
The average time in the system,
The average number of patients in the system,
The probability that the dispensary is empty,
The utilization factor of the system.

Introduction: In these instructions, we will use the example above (“Favorite Ice Cream Flavors and Gender Preferences”) as an example of a project to perform for this class. Please choose a different question to ask for your project, and use this as a guide for what your project will look like. Be sure that whatever question you ask, it represents a comparison of two different categories. For example, the question “Is there a predictive relationship between car type and gender?” would relate categories of car types (sedan, SUV, pickup trucks, hatchback, etc.) to gender (M, F, etc.).
Another example would be, “Does someone’s preferred media type change depending on generation?” This would relate media types like television, books, online text, online video, social media feeds, etc., to someone’s generation (Baby Boomer, Gen X, Millenial, Gen Z, etc.).
In the Ice Cream and Gender Preferences sample project below (your project must be different, but you can use this project as a model), we will investigate whether there is a significant association between people’s favorite ice cream flavors and their gender.
We will use the chi-square test for independence to analyze the data you collect and draw conclusions based on your findings. This project will help you understand how to perform and use hypothesis testing in the real world.
Materials Needed:
Data collection sheet (you can use any format that works for you).
Pens/pencils for data collection.
Computer or calculator.
Data Collection:
Formulate a plan to collect data from a sample of individuals. You can approach friends, family members, classmates, or any group of people willing to participate in your survey. (Note: this is a convenience sample, which does not generally yield valid results. You may put in more effort toward creating a better sample design, but please be mindful of the time we have left in the class.)
Create a data collection sheet with two columns: one for favorite ice cream flavors and one for gender. Include at least five different ice cream flavors and categories for male, female, and non-binary genders (if you choose).
Aim to gather data from at least 25 participants to ensure an adequate sample size for the chi-square test.
Data Entry:
Use your data collection sheet to organize your data into a contingency table with rows for each ice cream flavor and columns for male and female respondents.
Count the number of individuals who prefer each ice cream flavor for each gender and fill in the corresponding cells in the contingency table.
Submit a photo of this sheet for credit. Be sure to hold on to this sheet, since you will use it in future assignments.

I have wrote my discussion part but AI is high, please proffreading or editing make it no AI. But don’t change my content. 

hello please just write the data report that extracted from attached excel sheet .
please take a look to project sample PDF in attached files before writing the report .
please follow the instructions of assinment.

the Unit is 
Quantitative Methods for
Business and Management. it is mix between economics and  staticitics.  Please answer all the questions and also see thexcel sheet. 
no need for references 

in the document i uploaded, i already started on the data from the 2022 season. Follow the format that i have used so far to finish the data on the 2022 season, 2021 and 2023 seasons, also inclue weather and temperature. (note that there will be no odds data for the 2021 season, only for the 2022 and 2023 seasons)
use the following website to collect the odds for the games : https://oddspedia.com/american-football/europe/elf/odds.
the rest of the information(date and time of games, conferences, attendance, stadium…) can be found on Wipedia. weather and temperature can be found at the bottom of
