Math 160
Fall 2009
Exam 3 Review
Disclaimer: I have attempted to be comprehensive in the
following, but important items may have been omitted by mistake. If
you see such an omission, please let me know, but you are responsible
for all of the lecture material to date.
The third hour exam for Math 160 will be held on Friday, April 16, and
will cover chapters 5 and 6 in the textbook. In particular, be prepared
to:
- Be able to give definitions for the terms introduced in the exam
material. Once again, though you are responsible for all of the exam
material, the end-of-section summaries are a very good place to start.
- Be able to define the sampling distribution of a statistic.
- Be able to describe and use the binomial distribution.
- Be able to use Table C and the bottom portion of Table D
- Know the binomial mean and standard deviation.
- Know and be able to use the mean and standard deviation of a sample
proportion.
- Know the normal approximation for counts and proportions and the under
which this approximation may be used.
- Know the sample distribution of a sample mean (mean and standard
deviation)
- Be able to state and use the Central Limit Theorem.
- Be able to define, develop, and interpret confidence intervals.
- Be able to define and determine the margin of error, and the relation
between sample sizes and the margin of error.
- Be able to state null and alternate hypotheses and say what these are.
- Be able to define and use a z-test.
- Be able to define and calculate P-values and to use them to determine
whether or not to reject a null hypothesis
- Be able to give a careful definition of "statistically significant at
level α".
A calculator may be used for this exam, but only to calculate arithmetical
operations (add, subtract, multiply, and divide). You may not use the
statistical functions of your calculator on this exam.
