- 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; (8) Confidence interval, Degrees of Freedom, Estimator, Interval estimate, Maximum error of the estimate, Point estimate.
- Apply the normal distribution to solve an application problem. Look at problems 7.54 - 7.66*.
- 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 8.46*.
- 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*.

This is a group exam. The first page (problems 1 - 7) must be worked individually and turned in. The remainder of the test may then be worked with a partner. There is no requirement that you work with anyone else.
