Unformatted text preview: 2. Know definitions of Type I and II errors. 3. Know the consequences of Type I or II error. 4. For both ztests and ttests for testing hypotheses about a population mean μ, you will be expected to a. calculate test statistics b. find critical value based upon alpha c. make decision and be able to interpret for decisionmaking purposes. d. for the ztest, be able to calculate a pvalue 5. Know that for Hypothesis Testing for the population mean, either the population must be normal or the sample size must be at least 30. This ensures that the sampling distribution of sample means in normal. 6. For a ztest for proportions p, you will be expected to a. calculate test statistics b. find critical value based upon alpha c. make decision and be able to interpret for decisionmaking purposes. 7. Know that for Hypothesis Testing for the population proportion, This ensures that the sampling distribution of sample means in normal....
