Question

please help

Listed below are the division designations of teams that won a certain annual tournament, where N denotes a team from division N and A denotes a team from the other division, division A. Do the results suggest that either division superior? Use the runs test with a significance level of α=0.05. AANAANNNNAANNANNAAANNANAANAANAAAANNNNAAAA Determine the hypotheses. Choose the correct answer below. Ho: The data are in a random sequence. A. H: The data are in a sequence that is not random H: The data are in a random sequence. H: At least some of the data are in a sequence that is not random. OB. Ho: The data are in a sequence that is not random. c. Ho: The data are in a random sequence. Compute the test statistic (Type an integer or decimal rounded to two decimal places as needed.) Determine the critical values. (Use a comma to separate answers as needed. Type an integer or decimal rounded to two decimal places as needed.) Reach a decision. " Ho, because the test statistic is | There | ▼| sufficient evidence to conclude that the sequence is not random. Do the results suggest that either division is superior? O A. The runs test suggests that the sequence is not random, and teams from division N have won more of the annual tournaments than teams from division A, so it appears that division N is superior to division A B. The runs test suggests that the sequence appears to be random, but it does not test for disproportionately more occurrences of one of the two categories, so the runs test does not suggest that either division is superior. 。C.
