Directions

Use the drop-down menu to learn about the three steps needed to complete this assignment.

Three steps to complete the assignment

Step 1: Review the Rubric

• Before you submit your work, review the rubric at the bottom of this assignment.
• Use the rubric as a checklist to determine whether you are ready to submit your work.

Step 2: First Draft

• Commit a good-faith effort to address each item in the Prompt section below.
• Please be sure to number your responses and include “white space” between problem numbers. This improves the readability and flow of your work. I cannot give feedback and grade jumbled work.
• Use either of the following options to submit your work.
  OPTION 1: You can submit a text-entry assignment (i.e. typing your answers in Canvas). To learn how to submit a text-entry assignment, use these (opens in a new tab).
  OPTION 2: You can upload your paper-and-pencil work (or the digital equivalent). To learn how to upload your paper-and-pencil work, use these (opens in a new tab). WARNING – some file types may not be visible on my end. So to learn which files you can upload, be sure to use the directions link I provided for this option.
• Not ready to submit a good-faith effort yet? Avoid frustration – use the link to the Questions, Answers, & Tips discussion board (at the bottom of this page) to post questions about this assignment (or visit the discussion board to answer your classmates’ questions). You can also contact me directly (see the homepage for my contact information).

Step 3: Optional Final Draft

• After you submit your good-faith attempt to fully respond to the questions in the Prompt section below, advance to the ANSWER(S) page.
• You can use the ANSWER(S) page to correct your work and resubmit this assignment any time before I begin grading the problems. However, to earn full credit, you are not required to submit a final draft for this assignment. But if you do submit a final draft, I will only grade it if you submitted a good-faith effort on your first draft.
• Warning – I will only grade your most recent submission. So if you choose to submit a final draft, please do not leave anything out, and please do not direct me to read an earlier submission. To maximize your score, your most recent submission (at the time I begin grading) must be complete.

Prompt

Harris Interactive conducted a poll of American adults in August of 2011 to study the use of online medical information. Of the 1,019 randomly chosen adults, 60% had used the Internet within the past month to obtain medical information.

1. Use the results of this survey to create an approximate 95% confidence interval estimate for the percentage of all American adults who have used the Internet to obtain medical information in the past month.
2. Calculate the 90% confidence interval.
3. Which confidence interval has the smaller margin of error? Why does this make sense?
4. Which confidence interval is more likely to contain the true percentage of all American adults who have used the Internet to obtain medical information in the past month? Briefly explain your reasoning.

I need someone to carefully read the full assignment instructions and complete all questions step-by-step for Problem Set #4 (PPD 303: Statistics for Policy, Planning, and Development).

• Use the assignment details provided to solve every part correctly
• Use the attached Excel file (PS4.xlsx) for the questions that require raw data and Excel calculations, especially the matched-samples and independent-samples sections
• For Excel-based questions, you must show the exact formulas used with the full arguments entered not just the function names
• Show all work clearly and neatly, including how margins of error, test statistics, standard errors, confidence intervals, and P-values are calculated
• For the table-based parts, use the required statistical tables from the assignment (Table C for confidence intervals and Table A for approximate P-values)
• For the Excel parts, follow the professors directions exactly and provide the specific Excel formulas typed in to get the answers
• Answer the interpretation questions in plain English where required, including conclusions about statistical significance, P-values, Type I error, and Type II error
• For the matched-pairs question, calculate the change for each student and the average change before completing the hypothesis test
• For the independent-samples question, use the summary statistics given in the assignment and use the raw Excel data where the assignment specifically asks for it

Final deliverable requirements:

• Combine everything into one clean, organized PDF
• Make it neat, legible, and easy to copy into Word
• Clearly label each question number and each part
• Include all formulas, calculations, and written interpretations requested in the assignment
• Do not submit a separate Excel file as the final answer the final submission should be the completed work in PDF format

The professor is strict about showing work and formulas, so accuracy, organization, and clarity are very important.

NO AI USE. ALSO MUST BE COMPLETED BY OR BEFORE THE DEADLINE I GIVE.

I need help with my stats homework. I am going to provide all the information you need to complete it. NO USING ANY AI my professor can detect, so please do not put the assignment in AI, my professor will know, and the answers will not be correct, so I will receive a zero. Everything needs to be done by hand and imputed by hand. Thank you so much 🙂

Problem Set 4:

Your submission must be a single file (.pdf, .doc, or .docx). If parts of your submission are handwritten, be sure that your work is neat, legible, and organized. For questions requiring Excel, provide the formulas you used in your document. Do not submit the Excel file itself.

APPLICATION 1

ATTENDANCE WORKSHEET

The data pairs in the table are from 600 matched pairs of magnitude/depth measurements randomly selected from 10,594 earthquakes recorded in one year from a location in southern California. Only earthquakes with a magnitude of at least 1.00 are used. MAGNITUDE is magnitude measured on the Richter scale and DEPTH is depth in kilometers (km). The magnitude and depth both describe the source of the earthquake. The data are from the Southern California Earthquake Data Center. Use the table data to do the following: 1) Construct a histogram of the magnitudes. Use a class width of 0.50 and use a starting value of 1.00. Easy instructions for using a spreadsheet (they show Excel, but you may use Google Sheets) can be found here. You must upload your spreadsheet. You may not use AI, such as ChatGPT, etc. (15 points) 2) Looking at your histogram, which of the following comes close to describing the distribution: uniform, normal, skewed left, or skewed right? Briefly explain your choice. (5 points) 3) Consider the earthquake depths (in kilometers). a) Are the depth data categorical or quantitative? How do you know? (5 points) b) The depths are all rounded to one decimal place. Before rounding, are the exact depths that were measured discrete data or continuous data? How do you know? (5 points) c) Given that the listed earthquake depths are part of a larger collection of depths, do the data constitute a sample or population? Briefly explain your answer. (5 points) 4) Consider the paired magnitude/depth data. 2.45 MAGNITUDE DEPTH 0.7 3.62 3.06 6.0 7.0 3.3 1.09 5.4 0.5 3.1 2.99 17.6 0.0 7.0 2.58 2.44 2.91 7.0 15.9 3.38 2.83 11.7 7.0 2.44 2.56 7.0 2.79 6.9 17.3 2.18 3.01 7.0 7.0 2.71 2.44 7.0 7.0 8.1 1.64 a) Construct a scatterplot to determine whether there is a correlation between earthquake magnitudes and depths. Feel free to use a spreadsheet. However I encourage you to use Desmos as demonstrated in the notes. You may not use AI, such as ChatGPT, etc. You must turn in your scatterplot. If you use Desmos, click the Share icon and choose Share a Snapshot. A custom URL web address will be created for you to copy and paste. If you use Excel or Google Sheets, upload your file. (5 points) b) What is the correlation coefficient? Based on the result, does there appear to be a correlation? Briefly explain your answer. (10 points)
