STATS 220 Final Assessment Semester 1, 2020
Time Allowed: This Final Assessment has been designed so that a well-prepared student
could complete it within two hours. From the 1pm release time you will have 24 hours to
complete and submit your assessment. No marks will be deducted for taking longer than two

INSTRUCTIONS
This assessment is open book, you are permitted to access your course manuals and
other written material including online resources.
Calculators and computers are permitted.
It is your responsibility to ensure your assessment is successfully submitted on time.
We recommend you aim to submit a couple of hours in advance of the deadline, to allow
time to deal with any technical issues that might arise.
We STRONGLY recommend you download your submitted document from Canvas,
after submitting it, to verify you have uploaded the correct document.
This examination consists of 5 questions.
The marks for all questions sum to 100.
You should attempt ALL questions.
Questions are NOT worth equal marks.
For questions where you are required to write computer code, if you do not know the
exact code, you can still gain some of the marks by writing an approximation of what
the code should be.

Question Interpretation
Please note that during the final assessment period you cannot contact your instructors for
clarification on how to interpret the wording of any specific questions or to verify that your
answer is correct. Interpreting wording and making appropriate assumptions is part of what is
being assessed. You will need to interpret the question yourself and check your own answers.
If you believe there is a typo, first re-read the question to check you have not misunderstood
the question, as it is very common for students to misread questions. If you still believe there
is a typo, please phone the Contact Centre.
