State whether each standardized test statistic xf allows you to reject the null hypothesis. Explain. (a) x2 = 20.983 (b)x2 = 0 x = 28.8690 N (c)X = 1.782 (d) x2 = 28.887 2 so E. (a) Choose the correct answer below. O A. Reject the null hypothesis because the standardized test statistic is not in the rejection region. O B. Do not reject the nuill hypothesis because the standardized test statistic is in the rejection region OC. Do not reject the null hypothesis because the standardized test statistic is not in the rejection region. OD. Reject the null hypothesis because the standardized test statistic is in the rejection region. (b) Choose the correct answer below. O A. Reject the null hypothesis because the standardized test statistic is not in the rejection region. B. Reject the null hypothesis because the standardized test statistic is in the rejection region OC. Do not reject the null hypothesis because the standardized test statistic is in the rejection region. OD. Do not reject the null hypothesis because the standardized test statistic is not in the rejection region (c) Choose the correct answer below. O A Do not reject the null hypothesis because the standardized test statistic is not in the rejection region. B. Do not reject the null hypothesis because the standardized test statistic is in the rejection region OC. Reject the null hypothesis because the standardized best statistic is not in the rejection region OD. Reject the null hypothesis because the standardized test statistic is in the rejection region. (d) Choose the correct answer below. Next

x2 = 1.782 (d) x2 = 28.887 = D. Reject the null hypothesis because the standardized test statistic is in the rejection region. b) Choose the correct answer below. A. Reject the null hypothesis because the standardized test statistic is not in the rejection region. O B. Reject the null hypothesis because the standardized test statistic is in the rejection region O C. Do not reject the null hypothesis because the standardized test statistic is in the rejection region OD. Do not reject the null hypothesis because the standardized test statistic is not in the rejection region. (c) Choose the correct answer below. O A. Do not reject the null hypothesis because the standardized test statistic is not in the rejection region. O B. Do not reject the null hypothesis because the standardized test statistic is in the rejection region OC. Reject the null hypothesis because the standardized test statistic is not in the rejection region. OD. Reject the null hypothesis because the standardized test statistic is in the rejection region (d) Choose the correct answer below. O A. Reject the null hypothesis because the standardized test statistic is in the rejection region O B. Do not reject the null hypothesis because the standardized test statistic is not in the rejection region. OC. Do not reject the null hypothesis because the standardized test statistic is in the rejection region OD. Reject the null hypothesis because the standardized test statistic is not in the rejection region
