Math 170: Study Guide: Chapters 7 - 8
- Determine the probabilities associated with the standard normal distribution. Shade the
proper region under the curve. Six parts. Look at problems 7.6 - 7.39.
- Find a z-value when the area under the curve is known. Look at problems 7.46 - 7.48.
- Multiple Choice. Know the properties of the Standard Normal distribution.
- Multiple Choice. Know the properties of the Student's t distribution.
- Multiple Choice. Know the properties of the sampling distribution of the sample mean
(Central Limit Theorem).
- Multiple Choice. Know the properties of a good estimator.
- Definitions. Supply the term being defined. Four parts. Know the definitions of: (7)
Sampling error, Standard error of the mean, z value; Correction for Continuity (8) Confidence
interval, Degrees of Freedom, Estimator, Interval estimate, Maximum error of the estimate,
- True / False. Six parts. Look at the True-False questions at the end of the chapters*.
- Apply the normal distribution to solve an application problem. Look at problems 7.54 -
- Find the probability involving the sample mean and Central Limit Theorem. Look at
problems 7.100 - 7.117*.
- Find the cutoff scores for an exam so that a certain percent of the class receives a specific
letter grade. Look at problem 7.92.
- Approximate the binomial probability using the Normal distribution. Also give the actual
value using the binomial program on the calculator. Look at problems 7.130 - 7.139*.
- Find a confidence interval for the mean. Look at problems 8.10 - 8.16*.
- Estimate the sample size necessary to construct a confidence interval for the mean. Look at
problems 8.20 - 8.25*.
- Construct a confidence interval for the mean when the sample size is small. Look at problem
- Construct a confidence interval for the population proportion. Look at problems 8.49 - 8.59*.
- Estimate the sample size necessary to construct a confidence interval for a population
proportion. Look at problems 8.60 - 8.64*.
- Problems that are asterisked are directly from the book. When you are told to look at
problems, but there is no asterisk, the problem is similar, but not identical, to a problem from
- This is a group exam.
- Problems 1 - 11 must be worked individually and turned in.
- Problems 12 - 17 may be worked on with one other person.
- If there is an odd number of people taking the test, and no one wishes to work alone, then
there may be one group of three.
- You should decide who you want as a partner before the day of the exam, rather than coming
into the exam and seeing who is available.
- There is no requirement that you work with anyone else. You will be given the entire exam at
one time, but you may not get together with a partner before turning in the first section.
