General Guidelines

At the outset I want you to realize that this is an open book test, but full

preparation is absolutely necessary. If you are not prepared enough and need to

turn the pages of the book or power point slides or my Instructions at every step,then it would not be possible for you to finish all questions in time. Also remember

that the questions are based on the topics covered in the Text Book and my

Instructions but are not directly from the book (as was also true in your four Home

Assignments). That is why I am posting this guideline about 10 days ahead, so that

you have adequate time to review the whole material (which includes quite a lot :

more than 500 pages of the Text book, equal number of power point slides, and

several sets of My Chapter Instructions).

Also review the four Assignment solutions (you will receive the solution to thefourth assignment by the morning of Monday, July 1st.Therefore, no late

submission for any reason will be accepted for the fourth assignment. As

you have already seen, I give the solution to the Assignments with explanations

and details wherever I feel needed. Moreover, I provide hints and explanations in

my responses in the Virtual office Question Answer forum and in my prompt

responses to all your emails everyday of the week. I also provide power point

slides. But the most important resource for you to review and completely

master is the set of my own Chapter Instructions which covers everythingrelevant for Assignments and the Test.

Thus, you have enough resources available to prepare for the tests and

assignments. Having so many resources available, sometimes also creates a time

constraint problem in reviewing. Therefore, I will provide guidelines for the topics

you have to focus on, in the sections below. First, some general but important

reminders about logistics are in order: Keep at least one pen or pencil, a note

pad and a working calculator (with new batteries) so that you may be able to

do some calculations required for answering a question. Also keep the book

handy because you may need the appendix tables in some questions (or evenbetter, make a print out). And dont forget to save your work every five to 10

minutes during the test; because you may be timed out without realizing it or

some technical problems might arise. Above all, keep your computer in optimal

performing condition and have a backup plan for internet disruption at your home.

My best advice is that you learn how to use excel or MegaStat quickly (Not

essential for the test, but if you are smart and quick with these tools you may

get some of the answers quicker than the tables in the book and calculator).

However, for the test I am not asking you to use them. They are optional: you

can use them for your own convenience in getting the answers quickly. Another

advice is to start the test well before the last hours (that is well before 5 p.m. on

July 2nd). This will give you some time to contact me or the help desk if some

unexpected technical problem arises during the test. At the very last hour no one

will be able to help. If you take the test at the very last houragainst my advice,

then you are assuming all the risk/responsibilities on yourself for unforeseen

incidents. In the Final, that is not prudent.

Style and Format of the Test

The test will consist of 15 True/False type (8 points each), 15 Multiple/Choices (12

points each) and 10 Essay Type (20 points each) with a total of 500 points. The

Chapters covered are 4, 5, 6, 7, 8, 9, 10, 12, 13, and 14. The topics to focus in these

Chapters are listed below.

Chapter 4

1. The rules of Probability, Union and Intersection, Rules of Addition and

Multiplication, Mutually Exclusive and Not Mutually exclusive events, and

Complements,

2. Rules for Independent and Dependent Events

3. The Bayesian Rule

4. Contingency Table based Probability calculations

Chapter 5

1. The Concept of Discrete and Continuous Random Variables and Probability

Distributions

2. The Binomial Distribution: properties and problems based on applications ofbinomial distributions

Chapter 6:

1. Definition and properties of Continuous and Discrete random variables

2. Examples of Applying Normal Distribution (finding probabilities)

3. Finding X Values from given Probabilities for a Normal Distribution

4. Normal Approximation to Binomial Distribution

Chapter 7:

1. The Sampling Distribution of the Sample Mean, its Mean and Standard

Deviation or Standard Error, The Central Limit Theorem, the finite population

correction, and applications

2. The desirable properties of estimators: unbiasedness, consistency,

Efficiency/Minimum Variance

3. The Sampling Distributions of Proportions: its mean, variance, and standard

deviation or standard error, and applications.

Chapter 8:

1. Confidence Intervals for the Mean with known

2. Required sample size for given margin of error for Mean

3. Confidence Interval for the Mean with unknown

4. Confidence Intervals for the Proportions

5. Required sample size for given margin of error for proportions

Chapter 9:

1. Hypothesis Testing, Null and Alternative Hypotheses, Type I and Type II errors

and level of significance

2. The critical value, confidence interval and p-value approaches

3. Hypothesis testing for the mean of a Normal Distribution with known

4. Hypothesis Test for the Mean of a Normal Distribution when is Not Known

5. Hypothesis Testing for Proportions

Chapter 10

1. Test of Difference between two Sample Means with known population standard

deviations or variances (Z-test)

2. Test of Difference between two Sample Means when the Population Variances

are not known but are assumed Equal (the case of pooled Sample variance and t-

test)

3. Sampling Distribution of Difference between two Sample Means When

Population Variances are Not Known and are Assumed to be Unequal (t-test with

adjusted degree of freedom)

4. Paired Difference or the Case of Matched Pairs (t test)5. Test of Difference between two Population Proportions with Large Independent

Samples (Z-test)

Chapter 12

Chapter 14

1. Assumptions of the Multiple Regression Model

2. The Estimation, Interpretation and Prediction of a Multiple Regression Equation


5/5

3. The Explanatory Power: Coefficient of Determination and Adjusted Coefficient

of Determination

4. The Analysis of Variance (ANOVA) and the F-test

5. Tests of Significance of Slope Coefficients

6. Working with Partial (or Incomplete) Tables in Multiple Regression

You can use Excel/MegaStat (as many of you have done in the Assignments) orcalculate using calculator and formulas (as I have shown in the solutions and

Instructions). But you need to show key results and interpret/ explain or write fewwords of explanation in essay type questions, as most of you have done. If you

give one number or one word answer without any detail in essay type questions,you risk losing some (even if the answer is correct) or all points (if the answer is

wrong). Show me some key intermediate steps and results leading to the Finalanswer. You can simply copy and paste from your computer work or type the key

results and steps.

This concludes my Instructions for the Final. My final word of advice is that start

preparing for the Final from today and be prepared well in advance and take the

test at least keeping 10 hours or more between start and the final hour of the exam.That way you will have some time left if something unexpected happens. Keep

saving your work at about every 10 minutes. When you submit the test make sureit is properly submitted. It should tell you your score from the True/False and

Multiple Choices after submission. In the Final hours of the Final I may not be ableto help you (or the help desk may not be able to help) if some technical problem

occurs. During the Final they are also extremely busy helping large number ofstudents. You have about 10 days to prepare from today for the BIGGEST prize of

this course with 500 points, which can significantly change your grade in eitherway. Get the last Assignment done quickly and focus on the Final as early as

possible. You already know that I am practically accessible 24/7 through emailand questions in Virtual Office. But dont wait to ask questions when the window

period for the Final starts. I may be too busy or my internet may be down orsomething like that might happen at the last moment. So get ready before June 30th.

I wish Good Luck to everyone and congratulate on surviving this fast paced 4-weeks session on one of the difficult subjects in the program.

Cheers!
