Calculate the critical z-value(s) for each of the given hypothesis test scenarios below. If multiple critical values exist for a single scenario, enter the solutions using a comma-separated list. Round z-values to two decimal places. . Find the critical z-value(s) for a left-tailed test of hypothesis for a proportion, with a sample size of 113 and let a = 0.0005. 2 X . Find the critical z-value(s) for a right-tailed test of hypothesis for a proportion, with a sample size of 42 and a significance level of 1%. 2 . Find the critical >-value(s) for a two-tailed test of hypothesis for a mean, assuming the population standard deviation is known, with a sample size of 139 and let a = 0.02. Z . Find the critical z-value(s) for a two-tailed test of hypothesis for a proportion, with a sample size of 117 and a significance level of 20%. 2 = X
