Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis. 11) = 0.09 for a right-tailed test. A) 1.96 B) 1.96 C) 1.34 D) 1.34 12) = 0.08; H1 is 3. A) 1.75 B) 1.41 C) 1.41 D) 1.75 2 Chapter-8 Test-4 13) = 0.05 for a left-tailed test. A) -1.96 B) -1.645 C) 1.96 D) 1.645 Find the value of the test statistic z using z = p ^ - p pq n . 14) A claim is made that the proportion of children who play sports is less than 0.5, and the sample statistics include n = 1320 subjects with 30% saying that they play a sport. A) 14.53 B) 29.66 C) -29.66 D) -14.53 Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis (reject the null hypothesis or fail to reject the null hypothesis). 15) The test statistic in a right-tailed test is z = 1.43 A) 0.0764; reject the null hypothesis B) 0.1528; reject the null hypothesis C) 0.0764; fail to reject the null hypothesis D) 0.1528; fail to reject the null hypothesis 16) The test statistic in a left-tailed test is z = -1.83 A) 0.0672; fail to reject the null hypothesis B) 0.9664; fail to reject the null hypothesis C) 0.0672; reject the null hypothesis D) 0.0336; reject the null hypothesis 17) The test statistic in a two-tailed test is z = 1.95 A) 0.9744; fail to reject the null hypothesis B) 0.0256; reject the null hypothesis C) 0.0512; fail to reject the null hy
