Stats 12/8 test review

The final exam is scheduled for Monday at 4 PM.
The exam will encapsulate material from all previous four exams and is structured similarly to them.

The upcoming test is on Wednesday.
The test will consist of five questions:
- First two questions: Hypothesis tests for the population mean.
- Second two questions: Hypothesis tests for the proportion.
- Fifth question: A goodness of fit test.

It is advisable to have a sample problem for each type of question (mean, proportion, goodness of fit) readily available from your notes to reference during the test.
A hypothesis testing handout has been provided, which is a decision tree for determining and following the proper steps for conducting hypothesis tests. This handout is available on Brightspace and is linked within the course schedule.

Project deadline: Tomorrow (Wednesday).
Late submissions will be accepted on the day of the final due to late notice, however, timely submission is preferred for efficient grading.
Reminder: Projects must not be handed in early; doing so will lead to potential loss of the project materials.

The best approach to prepare for the final will involve reviewing the test solutions from previous tests. Once collected, the solutions will be posted immediately after the test.
The exam is open notes, and students should utilize StatCrunch as necessary.
It should be noted that while the problems may not be identical to past tests, they will cover similar concepts. Careful reading is advised as variations in questions could include different confidence levels.

Some common errors made by students include misreading questions based on previous tests and copying answers incorrectly. Pay close attention to details.
On the final, both the uniform and non-uniform goodness of fit tests will be covered. Students should be familiar with both:
- Uniform goodness of fit test: Easier as no calculations are needed.
- Non-uniform goodness of fit test: Requires calculation of expected values.

For hypothesis tests:
- p-values should be reported to four decimal places to allow conversion into percentage format correctly (two decimal places).
- Students should extract the mean and standard deviation from the data or given information when required.
Show work is expected particularly for the goodness of fit questions.

For confidence interval problems included in exams or finals, note that while interpretation may not always be explicitly required, it would be beneficial to prepare for any such prompts.
Students are advised to include necessary z-values charts in their notes. Standard confidence levels of 90%, 95%, and 99% can be used, along with the resources provided for finding these values.
When calculating sample size for proportions, use the formula involving prior estimates, denoted as p-hat (p̂), for accuracy.
In instances requiring calculations or critical values, students should consult Table 2, which associates the number of data pairs (n) with corresponding critical values.

Reference to stick to Test Two:
- Students were guided on how to approach statistical questions such as determining the probability of rolling numbers through sample space enumeration.
- When focusing on average calculations, step-by-step guidance exemplifies the expected practice in writing out sample spaces to count favorable outcomes.
Adjustments may occur in final grading based on performance in sections of the final exam corresponding to missed or failed tests, although these adjustments will not be reflected in Brightspace immediately following the exam.

The instructor will be available for any follow-up questions or further clarification until the exam dates. Students are encouraged to bring any additional queries they might have regarding the exams or their preparations before the final deadline.
