Is this value significant at a = 0.005? A. Yes, because the p-value is less than or equal to the alpha level. Therefore, the null hypothesis should be rejected. B. Yes, because the p-value is less than or equal to the alpha level. Therefore, the null hypothesis should not be rejected. C. No, because the p-value is greater than the alpha level. Therefore, the null hypothesis should be rejected. D. No, because the p-value is greater than the alpha level. Therefore, the null hypothesis should not be rejected. Meth Bus (385:02) Exam #2 04/05/23 Use the contingency table to the right to complete parts (a) through (c) below. a. Find the expected frequency for each cell. A B 1 Total 50 2 75 Total 50 75 125 Question 8 of 9 This test: 29 point(s) possible > This question: 5 point(s) possible (Type integers or decimals.) b. Compare the observed and expected frequencies for each cell. Choose the correct answer below. A. The totals for the observed values are always greater than the totals for the expected values. B. The observed values are always greater than the expected values. OC. The expected values are always greater than the observed values. OD. The totals for the observed and expected frequencies are the same. c. Compute X STAT. Is it significant at a = 0.005? First let , be the proportion of all events of interest in A, and let be the proportion of all events of interest in B. Determine the hypotheses. Choose the correct answer below. OA. Ho: 12 C. Ho =2 OB. Ho OD. Ho: Calculate the test statistic. XSTAT (Round to two decimal places as needed.) What is the p-value? p-value (Round to three decimal places as needed.)
