• Define each of the following terms:
• Hypothesis testing,
• Null and alternative hypothesis,
• Non-directional and directional hypothesis,
• Type I error in testing hypothesis,
• Type II error in testing hypothesis, probability of type I error (ɑ),
• Probability of type II error (ß),
• Power of the test and its significance, the critical value(s) in a test,
• p value (significance level).
• What is the difference between testing hypothesis on a population and testing hypothesis when comparing two populations? Provide hypothetical examples.
• What are the possible outcomes in testing a hypothesis?
• What are the determinant factors in deciding the critical value(s) in testing a hypothesis?
• When the z statistic is appropriate to be used in testing a hypothesis?
• When the t statistic is appropriate to be used in testing a hypothesis? For each case, include the underlying assumptions, and the test statistic, for both testing a hypothesis on the mean of population, and testing hypothesis in comparing the value of the mean in a population with the value of the mean in another population.
• What is the criterion for rejecting the null hypothesis for both non-directional and directional tests? How do you find the p value in each case? Do not forget to discuss cases that involve proportion(s).
• When is the chi-squared statistic used in testing a hypothesis? Include underlying assumptions and the test statistic for testing a hypothesis on a single population.
• What is the criterion for rejecting the null hypothesis for both non-directional and directional tests?
• How do you find the p value in each case?
