Remarks:

1) The final exam will cover chapters 1 through 11 (no 9.5).

2) Since some students may live in different time zones, the time observed for this class is PDT. (Pacific Daylight Saving Time)

3) Exams will be available the day of the test for 24 hours beginning at 12:01 am PDT. Students will have 4 hours to complete a test within the 24 hour period. Once you start the exam, you cannot pause and continue later.

4) Quizzes will be assigned with a deadline as well. There are 2 attempts per quiz.

5) Once in the website, go to MULTIMEDIA LIBRARY. In this area students will find eight different options for course instruction. These options include video lessons and Problems solved. This is the main form of instruction.

6) A student who scores below 50% on the final exam will be assigned a grade of a

D or an F, that is regardless of the final score for the course.

The Exams

1st Exam. The first exam will cover chapters 1 through 4. Chapters 1 through 3 are mostly concepts and few applications. Chapter 4 is about counting and Probability.

2nd Exam. The second exam will cover chapters 5 and 6. We start working with discrete random variables and conclude working with continuous random variables and normal distributions.

3rd Exam. The third exam will cover chapters 7 and 8. We start working with confidence intervals and hypothesis testing for one population.

4th Exam. The fourth and last exam will cover chapters 9, 10 and 11.

Quizzes.

I will make available 2, 3 or 4 quizzes per exam for a total of 12 quizzes for the semester. Each quiz contains 10 questions, a point each. The total value of all quizzes is 25% of your overall grade. You may submit answers to every quiz up to two times.

How Many Hours per Week is Enough to be Successful?

Past studies reveal that for every hour of instructions, a student will need to spend 2 times more hours working on assignments such as quizzes and homework.

In a summer semester class, we need to work an average of 18 to 24 hours per week.

What Are The Course Objectives?

The successful student, by the end of the semester, will be able to:

1. Collect data appropriately.

2. Identify the instances where data has not been properly collected.

3. Summarize data in graphs and charts.

4. Construct Frequency Distributions.

5. Find the mean, standard deviation, variance and apply the empirical rule.

6. Build a Probability Distribution using a Frequency distribution.

7. Identify a Probability Distribution and a Binomial Distribution.

8. Find probabilities using Normal Distributions.

9. Find probabilities using t distributions.

10. Find estimates using point estimates and error formulas.

11. Answer claims using detailed procedures.

12. Finding linear correlations and regression equations.

13. Apply non-parametric methods

Students completing Math 140 will be able to:

(1) Construct a histogram for a given set of data. This can be done by hand or with a graphing calculator.

(2) Construct a single-sample confidence interval, and draw an appropriate conclusion. This can be done by hand or with a graphing calculator.

(3) Construct a single-sample hypothesis test based on a given claim, and draw an appropriate conclusion.

Good luck this semester!
