In the exercises below, we have given the value obtained for the test statistic z in a one-mean z test. We have also specified whether the test is two-tailed left-tailed or right-tailed. Determine the p-value in each case and decide whether, at the 5% significance level, the data provides sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis.  2.1 Right tailed test: a. z = 1.24 b. z = -0.69 2.2 Left-tailed test: a. z = -0.74 b. z = 1.16 2.3 Two-tailed test: a. z = -1.66 b. z = 0.52
