1.Z-Test: 1 ∝.: Single sample hypothesis testing for the population mean, ∝, with known population variance, or for large samples with unknown population variance.

2.Z-Test: ∝1−∝2.: Hypothesis testing for the difference of the population means, ∝1- ∝2, 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 ∝.: Single sample hypothesis testing for the population mean, ∝, for small samples with unknown population variance.

6.T-Test: ∝1−∝2.: Hypothesis testing for the difference of the population means, ∝1- ∝2, for small samples with unknown population variances.

Try the following exercise:

Example 1 – For ∝0 = 150, σ = 10,  x = 158, n = 50, for α	= 0.05, test the
hypothesis H0: ∝ = ∝0, against the alternative hypothesis, H1:	∝ ≠ ∝0.
