1. One-population hypothesis tests. A. Numeric data 1. Perform a T test to test the claim that the population mean is different from the value given, using your value of s. 2. Use the TI to obtain the same test. 3. Perform a hypothesis test to test the claim that the population standard deviation is different from the value given. Use the given population standard deviation for this part only. B. Yes/No data 1. Perform a hypothesis test to test the claim that the population proportion is different from the value given. 2. Use the TI to obtain the same test. II. Two-population confidence intervals A. Numeric data-Choose the person whose mean is furthest away from your mean. 1. Calculate the 95% confidence interval for the difference of the two means. 2. Use the TI to obtain the confidence interval. B. Yes/No data-Choose the person whose proportion of yes responses is furthest from yours. 1. Calculate the 95% confidence interval for the difference of the two proportions. 2. Use the TI to obtain the confidence interval. Note: For all hypothesis tests, use a = 0.05.
