*Please reach me by e-mail via Angel. Make sure that the subject begins with Stat 319. I will send
e-mails via Angel as well. It is your responsibility to check e-mails regularly.
Course Material:
Textbook: Modern Mathematical Statistics with Applications, 1st Edition by Devore and Berk
Slides: I will upload course lectures (pdf files) on Angel at least the day before the lecture. You
are responsible to print them and bring them to class. Slides will contain the most important
material of the book. I expect that you will read the book in order to see more details and see
more examples.
Schedule: The slides for each lecture will be informative of what you should read and which
exercises you will be able to solve from the book. So if you miss a class, find the lecture slides
in Angel. For further help, you are encouraged to come and find me.
Calculator: You will need a scientific calculator for this class.
Prerequisites:
 Stat 318 or basic knowledge of probability
Topics:
 Statistics and their distributions
 Introduction to point estimation
 Introduction to interval estimation
 Hypotheses and Test Procedures for one sample
 Hypotheses and Test Procedures for two samples
 Non-parametric test procedures for two samples
 Single Factor ANOVA (test procedure to compare more than three samples)
 Simple Linear Regression (finding if there is a relation between two variables)
 Goodness of fit tests
Academic Integrity:
All Penn State and Eberly College of Science policies regarding academic integrity apply to this course.

Goal:
The purpose of this class is to introduce students into the basics of applied statistics using basic
knowledge of probability. You will be introduced into different procedures for estimating and
testing for unknown parameters of a probability distribution.
Objectives:
By the end of the semester students are expected to:
 Demonstrate their ability to find estimators for unknown distribution parameters.
 Understand a problem, and be able to “decode” it, that is, transforming English language
into statistical symbols.
 Be able to choose and write down the correct hypothesis test that is needed on any given
problem.
All the above will be demonstrated through the various problems that we will discuss in class
and the problems that will be given on the exams and the quizzes.

Homework:
 Every lecture I will give you suggested homework problems from the book. It is for your
pleasure and practice.
 I suggest you to solve as many exercises as you can.
 Why is it a good idea to practice with them, if I am not going to grade them? Each week I
will give an extra credit assignment consisting of 3-8 Exercises. The assigned questions will
be given in the homework folder. To get the extra points you have to turn them in, by the
beginning of the lecture they are due. Each assignment will give you 0.5-1 extra credit
points. (that means at least 7 extra credit points)
 To earn an extra point, you need to finish all the questions assigned and please do them
neatly for a TA to check your work. No Homework will be accepted by email.
Chapter Quizzes:
 Chapter Quizzes will be given after the end of each Chapter. I will inform the class at least
one week before the day of the Quiz.
 We will have 6 Chapter Quizzes as follows:
Quiz
Material
Quiz 1
Chapter 6
Quiz 2
Chapter 7
Quiz 3
Chapter 8
Quiz 4
Chapters 10 (and 14)
Quiz 5
Chapter 11
Quiz 6
Chapter 12
Note: Chapter 14 may be included depending on the pace of the class.
 I will count your best 5.
 No make up Quizzes will be given.

Exams:
 Midterm 1: Chapter 9
 Final: Chapters 8, 9, 10, 11, 12, 13 (and 14)
Note: Chapter 14 may be included depending on the pace of the class.
Makeup Policy:
 No make-up Quizzes will be given.
 If you must miss the Midterm or Final, speak to me BEFORE the date of the exam in order
to set up a conflict exam time. Otherwise you will receive a zero for the missed exam.
 You will not be able to negotiate missed exams and quizzes at the end of the semester.
 You have one week after the grades are given to discuss the grades for both quizzes and
midterm exam.
Grading Scale:
93 ensures at least an A
90 ensures at least an A 87 ensures at least a
B+
83 ensures at least a
B
80 ensures at least a
B77 ensures at least a
C+
70 ensures at least a
C
60 ensures at least a
D
Anything less than 60
F
These are tentative and could be lowered depending on how final course scores turn out.
Some useful notes:

No essential homework means the class goes at the bottom of the stack. The easiest
way to avoid this is by forcing yourself to study at least X hours every week for the class.

The value of X in the above phrase should be decided by each one of you, based on
your needs. I expect that an AVERAGE student will need 3 to 4 hours of study per week.

Try not to stay behind early. In this course everything is building on previous
Chapters. You do not want to stay behind.

If you have a question, don’t be shy. Everyone has weaknesses. If you don’t expose
them, and most critically, if you don’t let me help you overcome those weaknesses, the
whole class will be a bad experience for you.
