9. Suppose you have used a randomized block design to Treatment help you compare the effectiveness of three different Block treatments, A, B, and C. You obtained the data given in the table to the right and plan to conduct a Friedman F-test. Complete parts a through c below. OIAWN. 17 18 9 17 a. Specify the null and alternative hypotheses you will test. Ho: (1 ) the probability distributions for the (2) is/are (3) Ha : (4) the probability distributions for the (5) is/are (6) b. Specify the rejection region for the test. Use a = 0.01. F. (7) (Round to three decimal places as needed.) c. Conduct the test and interpret the results. Find the test statistic Fr F. = (Round to two decimal places as needed.) Interpret the results. (8) the null hypothesis. There (9). sufficient evidence to support the alternative hypothesis that (10) of the probability distributions for the (11). are (12) (1) O At least two of (2) O 5 blocks (3) O identical (4) O All of (5) O 5 blocks (6) O identical (7) O (8) O Do not reject (9) O is O All of O 3 treatments O different O At least two of O 3 treatments O different O
