2. Z-Test: µ1−µ2.: Hypothesis testing for the difference of the population means, µ1- µ2, with either known population variances, or for large samples with unknown population variances. 3. Z-Test: 1 p.: Single sample hypothesis testing for the proportion, p, for large samples with unknown population variance. 4. Z-Test: p1− p2.: Hypothesis testing for the difference of two proportions, p1-p2, for large samples with unknown population variances. 5. T-Test: 1 µ.: Single sample hypothesis testing for the population mean, µ, for small samples with unknown population variance. 6. T-Test: µ1−µ2.: Hypothesis testing for the difference of the population means, µ1- µ2, for small samples with unknown population variances. Example 1 - For µ0 = 150, σ = 10, ⎯x = 158, n = 50, for α = 0.05, test the hypothesis H0: µ = µ0, against the alternative hypothesis, H1: µ ≠ µ0. Press ,Ù--@@@OK@@@ to access the confidence interval feature in the calculator. Press @@@OK@@@ to select option 1. Z-Test: 1 µ. Enter the following data and press @@@OK@@@: You are then asked to select the alternative hypothesis: Select µ ≠ 150. Then, press @@@OK@@@. The result is: Page 16-10
