1. Find the critical value and rejection region for a left – 2. Find the critical values and rejection regions for a two- tailed test with significance level of 1% or a = 0.01. tailed test with a = 0.05 Since the test is left – tailed, then the critical value (z) Since the test is two – tailed test, the critical region corresponds to an area of 0.01. corresponds to - a = 0.025 and 1 – – a = 0.975. Using the z- table, identify an area as close as possible to the given area. This area falls between z = -2.32 and z = - 2.33. We get the critical value for a = 0.01 by getting the areas 0.025 and 0.975 are -1.96 and 1.96, respectively. So, mean of the two z values: z, =- Using the z – table, the z- scores that correspond to the - 2.32 + -2.33 the critical values are zo = -1.96 and z=1.96. --2.325. The rejection regions are to the left of -1.96 and to the right of 1.96. Thus, the critical value is zo = -2.325 or -2.33. 1 a = 0.025 = 0.975 a = 0.01 =, =-2,33 =, = -1.96 =, =1.96 АCTIVITY A.
