Use the following contingency table to complete (a) and (b) below. A B C Total 15 25 50 90 2 55 50 55 160 Total 70 75 105 250 a. Compute the expected frequencies for each cell. A B C N (Type integers or decimals. Do not round.) b. Compute XSTAT . Is it significant at a = 0.01? Set up the null and alternative hypotheses to test. Choose the correct answer below. OA. HO: My = 12 OB. HO: TA = IB = IC Hy: Not all it are equal (where j = 1, 2) Hy: Not all it are equal (where j = A, B, C) O C. Ho: Not all my are equal (where j = A, B, C) O D. Ho: Not all it; are equal (where j = 1, 2) H1: TA = TB = KC H1: 1 = 12 Compute XSTAT . XSTAT = (Round to three decimal places as needed.) Find the p-value. p-value = (Round to three decimal places as needed.)IS XSTAT Significant at a = 0.01? O A. Yes, because the p-value is less than the level of significance. O B. Yes, because the p-value is greater than or equal to the level of significance. O C. No, because the p-value is less than the level of significance. O D. No, because the p-value is greater than or equal to the level of significance
