Let n, = 40, X1 =30, n2 = 40, and X2 = 20. Complete parts (a) and (b) below. a. At the 0.01 level of significance, is there evidence of a significant difference between the two population proportions? Determine the null and alternative hypotheses. Choose the correct answer below. OA. HO: Ty ST2 OB. HO: Ty # 12 H 1: It 1 > T 2 H1 : It 1 = 1 2 O C. Ho: T1 = 12 OD. HO : T 1 2 12 Hy : Ty # 16 2 H1 : Ity O H1: HD CO O C. Ho: HD =0 (where HD = H1 - H2) OD. Ho: HD #0 (where HD = H1 - H2) H1 : HD # 0 H1 : HD = 0 Determine the test statistic, tSTAT- tSTAT = 1.82 (Round to two decimal places as needed.) Find the p-value for the test statistic. The p-value is 0.039 (Round to three decimal places as needed.) State your conclusion. Do not reject Ho. There is insufficient sufficient evidence to conclude that the mean adindex ratings are higher for cola B than for cola A
