Please write out the answer and explain step by step. dont use chat gpt or another online writig service as this paper is run through plagirms detector. I added an abstract page but you dont have to write one, The reason why i added it was to raise the price as it only cost 10, and i think the work should cost more 

Please answer the questions in the 3 attached files. Two attachments has 2 questions each
and the 3rd attachment has 3 questions with multiple parts.

Copy all outputs into Word document.
2) Repeat all the steps but with 500 number of trials. Copy all outputs into Word document.
a)  State the 95% confidence interval to three decimal places.
b)  What is the sample proportion to three decimal places? What is the test statistic?
c)  Based on the p-value, would you reject or fail to reject the null hypothesis at 0.05 significance level? Explain.
a) State the 95% confidence interval to three decimal places. Did the interval get wider or narrower? Explain.
b)  What is the sample proportion to three decimal places? What is the test statistic?
c)  Based on the p-value, would you reject or fail to reject the null hypothesis at 0.05 significance level? Explain.

Place the answers in the answer space you made . Provide the solutions to the examples on separate pages in the numerical order of the problems. Examples with out solutions will not be granted partial credit. Each correct answer is worth 4 points.

The purpose of this assignment is to improve your skills using equation editors and graphing tools. You will graph trigonometric functions by hand and with the use of online programs and evaluate some trigonometric expressions without a calculator.
Complete both problems. Your first problem will be assigned by the first letter of your last name as it appears on the class roll. Guidance is provided in the Discussion Questions document on how to complete each problem. Include both your solutions and hand sketches in your document and submit them as one PDF document for your initial discussion reply.
ATTACHED IS THE QUESTIONS. MY LAST BEGINS WITH THE LETTER “M”.

Overview and Objectives
In this assignment, you will be doing your own statistical analysis from a data set you find online or in a newspaper/magazine. The statistical analysis will include items such as mean, median, 5 number summary, IQR, boxplot, standard deviation, range and z-score.
What you will Submit
You will be submitting your assignment as a PDF. In the submission, you must include a link to the article where you found your data set from, or a picture of your physical article from a newspaper/magazine.
Instructions:
Read the entire assignment. Make sure to complete all questions for the assignment.
To help you understand the directions for the assignment, watch the video below before completing the assignment.
Assignment:
In a newspaper, magazine, or on the internet, find an article that contains a data set of 15 or more values. Apply what you are learning about statistics to analyze the data and discuss the data within the context of the article. Follow the steps below, showing how you did all calculations.
Include the link to the article, or use a screenshot of the article that shows all of the data values.
Based on the data, tell the units of the variable. For example, in an article about a basketball player, the units might be the number of points scored per game, the number of games played per season, or the percentage of scored free throws.
Does the article describe the data using any statistics, such as an average or a range? If so, describe what statistic was used and how to calculate it. If the article didn’t state any statistics, give one statistic that could have been helpful to include and explain why it would be good to include.
Calculate the following statistics from the data. Show all your written work, or include an accessible link to the spreadsheet you used to do the calculations.
Mean and median
5 Number Summary, IQR, and boxplot
Standard Deviation (tell whether it is population or sample, and calculate it accordingly) and range
Ask a question about the data that can be answered using a z-score and probability. You will need to assume the data is normally distributed, which may not be true. An example could be, “What is the probability that this basketball player will score fewer than 15 points in their next game?” Then answer your question using the statistics you calculated, the z-score formula, and the z-score table.
Use the statistics you calculated to write a short analysis of the data. Use the context of the article to relate the numbers to the original topic. Ideas include describing the center and spread of the data, relating the mean and median if they are very different, or describing the spread of the data based on the 5 Number Summary. A specific example could be, “Although the player scores an average of 20 points per game, the standard deviation being 8.34 means that the number of points scored is highly variable. This might mean that the player has good games and bad games because the large variation means they are not consistent in the points they score.”
Submitting Your Work:
Click on the “Add Submission” button to upload a text document. PDF is the required file format. (From Word, choose ‘save as’ from the file menu; select PDF as the file format. From Google Docs., go to the File Menu and select Download as a PDF). We cannot open other file formats, e.g., .pages, .heic, etc., and do NOT accept a Shared Google Doc. Alternatively, you can use the text box on the submission page. You can create tables, add images, etc., using the formatting tools; click the first button on the menu bar to access them.
If your article is from a physical newspaper/magazine, you will need to either scan or photograph it. Make sure you save the image in a common file format; PDF is always the preferred file format. However, you can also use JPEG, GIF, or PNG. We recommend you put your file on a shared hard drive like Dropbox, Google Drive, iCloud, One Drive, etc. Use the online text box to provide us with the URL to the file. Remember to set the permissions on the file to ‘anyone with a link’.
Review the ‘submitting your assignment’ document we provided at the beginning of the course for more details.

Assignment Objective:
The aim of this assignment is to deepen your understanding of how probability is applied in various contexts through the analysis of a selected reading material. Your discussion should be accessible to fellow students with a basic understanding of probability and engineering, without assuming specialized knowledge in your specific subject area.
Assignment Guidelines:
Summary of Material:
Provide a brief overview of your chosen material, aimed at a general audience. You can typically find this information in the introduction of the paper.
Application of Probability:
Describe how probability is used within the paper. For instance, it might be employed to model a process such as the velocity of wind affecting a bridge.
Probabilistic Concepts:
Discuss the specific probabilistic concepts used in the paper. Highlight whether these concepts are part of our course syllabus or if they extend beyond it. Discuss how these additional concepts either add complexity or enrich the paper’s approach.
Contribution of the Probabilistic Model:
Evaluate what the use of a probabilistic model adds to the discussion in the paper. Consider whether the model complicates the paper unnecessarily or whether it simplifies a complex issue too much. Discuss any new perspectives the probabilistic approach offers on the subject.
Alternative Probabilistic Approaches:
Consider other ways probabilistic concepts could be introduced in the subject. Assess whether the author’s chosen method was appropriate or if there might have been a better alternative.
Effectiveness of Probabilistic Usage:
Critique the author’s use of probabilistic concepts. Decide whether their application was appropriate and accurate, or if it was misguided or incorrect.
Submission Instructions:
Submit your work as a typed PDF via the Teams assignment portal.
There is no strict length requirement, but aim for no more than 3 pages, single-spaced, with a font size of 10.
Include a link or provide reference information for the article, chapter, blog, etc., that you are discussing.
I’ve attached the article for this assignment. Could you please read it and prepare a summary of the research findings? Your help with crafting the paper would be greatly appreciated. Thank you!
