Midterm 2 Procedures

Duration and timing

The exam is exactly 60 minutes long.
You may fill out the front page before the exam starts.
During the exam, write your name on every odd numbered page. This cannot be done after time is called.

Breaks and leaving the room

No breaks are allowed during the exam.
If you leave the exam room, you must turn in your exam and you cannot return.

Exam format

The exam begins with:
- 1–6 True or False questions, 2 points each
- 1–6 Multiple Choice questions, 3 points each
The remaining questions are free response.
Unless stated otherwise, report numeric answers to four decimal places.

Graphs, work, and interpretation

If graphs are needed, they will be provided, except possibly a modified boxplot.
Graphs will be labeled so you know what they are for.
You may use the provided graphics to answer questions. However, any numbers you use that are not given in the question (and not computed in earlier parts) must have supporting work shown.

Code recognition

You will not be required to write code, but you will be required to recognize code and interpret output.

Allowed materials

One 8.5 × 11 inch crib sheet is allowed.
- You may use both sides.
- It may be typed or handwritten.
- You may include anything you want.
- Strong recommendation: organize it for fast lookup (for example, boxes, headings, color coding for formulas, definitions, theorems, and techniques).
A scientific calculator is required.
A z table is not needed for this exam. Any critical values or quantiles you need will be available from code output.

Desk policy and personal belongings

The only items allowed on your desk are:
- writing utensils and erasers
- scientific calculator
- picture ID
All other personal belongings must be stored away (backpack, purse, etc.).
Once the exam begins, you may not open your bag unless given permission by the instructor.
If you need scratch paper, raise your hand and it will be provided.
- Write your name in the upper right corner of all scratch paper.
Your phone must be stored away and cannot be at your desk.
You may not share anything with anyone else in the room.

Submitting the exam

Turn in your exam at the location assigned by your instructor.
You must show your PUID (or another ID with instructor permission) and sign the attendance sheet for your section.
You must turn in all papers, including:
- the exam
- any scratch paper
(Note: a z table is not required for Exam 2.)

Grading policy

Grading emphasizes consistency across parts.
If a later part depends on an earlier result, we will grade the later part based on your earlier answer, even if the earlier answer was incorrect.
If you do not know how to do an earlier part, write something plausible so dependent parts can still be graded.
If you write an impossible value (for example, a normalization constant that makes a PDF negative or identically 0), you will lose points on dependent parts.

Returning exams

Exam 2 covers material from chapters 7-11
