 Project 3 - Now available for your viewing pleasure.

Exam 3 Info:

You may have three one-sided pages of notes plus the handy-dandy pullout chart (if you wish).  I will provide the t-chart and the r-chart attached to the exam.  You should also have your calculator to use during the exam.

The overall exam contains approximately:

4 Hypothesis tests (40 points each = 160 points):  µ, p, p1 – p2, correlation

4 hypothesis test concepts (40 points): critical values, p-values, tails, Ho, H1

4 (80 points) probability, proportions, point estimates, sampling methods. 

4 Confidence Intervals & concepts (80  points):  µ, p, p1 – p2; pt-estimates, errors, three ways to write C.I.,  sample size, requirement check

2 Normal Distribution, Central Limit Theorem (Ch 6) (40 points)

 

These are the instructions that are on the first page of the exam of how I expect to see the hypothesis tests:

FOR ALL HYPOTHESIS TESTS for p, μ & σ YOU MUST:

A) State the Ho & H1 in symbolic form if not given that way.

B) Sketch the curve (or number line) correctly and label the type of curve (if applicable): normal/student-t

C) Shade the appropriate tail(s), labeled with the correct area inside the tail(s).

D) Label on the curve all other values used:

-If you use the test statistic method, then also include the critical value(s), the test statistic

- If you use the p-value method you must still draw parts B & C.

E)  State:  “reject Ho”  or “fail to reject Ho” and WHY.  If you don’t state this part then you can’t earn credit for the conclusion (part F).  

F)  State the conclusion correctly, as appropriate for a general audience, specifically referring to the described situation.

 

Grades are based on a points: (See syllabus for more details)

Homework = 40 points each     Quizzes = 20 points each
Class Activities = 30 points       Exams = 400 points each
Projects = points vary              Final Exam = 500 points 
Must earn 65% on final exam AND have sufficient points earned to pass the course.  
Grades will be rounded up if Final exam is the higher of the two grades AND 80% of HW and CA have been completed.

Assignments:

Instructions for video portions of the assignments:  Scroll down to “Training Videos” on the course webpage.  Then look under the appropriate chapter for the video.  Take notes while watching the videos.  For some videos fill-in notes are provided (by clicking on the link and printing.  For the first few I have printed these out, but after that you will need to print your own using the link.)  For videos without fill-in notes provided you need to do your own notes or answer a response question.  If there are no instructions next to the video then take notes on the video and write the definition/description of the main concepts. Turn this in with your HW.  Be sure to write the TITLE of each video above EACH of your video notes.

HW Notes: For selected sections you will be reading the text and filling out notes and answering self-check questions.  Turn these in with the HW.

Instructions for Vocabulary: Make a list of pertinent vocabulary for EVERY section of HW that you turn in. Do this for each NEW section covered in the HW.  Be sure to label what section EACH vocabulary is from.  (You do not need to redo vocabulary for sections already covered on previous HW.)

General HW instructions available with tentative schedule by clicking on your section number at top of this page. They were also handed out on the first day of class. Be sure to read the general HW instructions to avoid losing points.

Book Problems: (≈ 3.5 hours)

For all hypothesis tests, you MUST draw a picture of the distribution and the area being tested.  Then, draw the information on the graph that shows you how you came to your conclusionFinally, state your conclusion including the appropriate interpretation of your conclusion (i.e.  go through all the steps you learned to do in class)

Hypothesis Test Answer Key (use this to check for solutions that are consistent with how we write our conclusions in class.  For the most part, you only need these for not equal to tests, and even numbered problems.  This answer key does NOT contain the entirety of the solutions nor does it have all the solutions, this is a supplement to help you not be confused by the inconsistency of how the book writes up the conclusion sentences.)

Videos:  (≈1.3 hours) Take notes on each of the videos.  Turn them in with HW.

  • McDonalds vs. Drugs cc (22:00)   OPTIONAL  This is an optional but thought-provoking video.  It has crude and foul language due to the nature of the topic as this is a study of a gang in Chicago quite a few years back and has direct (unedited) quotes from the members.  If you do watch this think about the statistics he uses and whether you think his use of statistics here proved his point.  If you take decent notes on it you can earn an extra 4 points on your HW.
