STA 199: Exam 02

Instructions

  • The exam questions are in the README portion of your repository entitled “exam02-GitHubUsername” at the GitHub course organization page.

  • Open the .Rmd file and replace “Your Name” with your name.

  • This exam is due Monday, June 20 by 8:59am.

  • You must submit a PDF document to Gradescope that corresponds to an .Rmd file on your GitHub repository in order to receive credit for this exam.

    • If a PDF is not uploaded to Gradescope by the submission deadline, your latest commit prior to the deadline will be used as your submission.
    • There will be a 5 percentage point penalty for failing to submit a PDF to Gradescope.

  • Commit and push often and at appropriate times. Part of your grade will be based on quality of commit history.

  • With the exception of major emergencies, late submissions will not be accepted. In the case of a major emergency, you should have your Dean send the instructor an excuse.

  • Start and submit the exam early in order to avoid any last-minute technical issues.

  • You may resubmit the exam before the deadline.

Rules

  • This is an individual assignment.
  • Everything in your repository is for your eyes only.
  • You may not collaborate or communicate anything about this exam to anyone except the instructor. For example, you may not communicate with other students, the TA, or post/solicit help on the internet, email or via any other method of communication.
  • You may use R, as well as any notes, books, or existing internet resources to answer exam questions. If you use a resource outside of those we used for class, you should cite it.
  • You must cite any code you use as inspiration. A failure to cite is plagiarism. Cite any sources by providing a link to the original source in your exam write-up.
  • No office hours will be held while the exam is live.
  • Do not email the TA with questions.
  • If you have questions, email the instructor. Questions should only be about understanding the data or the exam’s instructions. You may not ask questions on any topics from past assignments or material related to the exam. Note: questions asked between 7:00am and 12:59pm Monday the 30th may not be answered.
  • The instructor will provide code debugging if needed, but this will result in a grade penalty if needed.

Academic Integrity

By taking this exam, you pledge to uphold the Duke Community Standard:

  • I will not lie, cheat, or steal in my academic endeavors;
  • I will conduct myself honorably in all my endeavors; and

Submission

Please only upload your PDF document to Gradescope. Before you submit the uploaded document, mark the pages associate with each exercise. If any answer for an exercise spans multiple pages, mark all pages. Make sure to associate the “Workflow and formatting” section with the first page. Failure to mark the pages in Gradescope may result in point deductions.

Make sure that your uploaded PDF document matches your .Rmd and the PDF in your repository exactly. Points will be deducted for non-reproducibility.
