(b) Find the values of SS(treatment) and SS(error). (c) What conclusion can you draw about the hypothesis test in (a)? Use a = .05. (A) Ho: 1 2 3, H: = ; for at least one pair (i,j) (B) H0 = 2 = 3, H: ; for at least one pair (i,j) (C) Ho: 2 3, H: = ; for all pairs (i, j) (D) H0 = = 3, H: M #2 3 (E) H0 = = 3, H: ; #; for all pairs (i, j) Problem #1(a): B hypothesis tested Problem #1(b): SS(treatment), SS(error) (numbers correct to 4 decimals) (A) Reject Ho since 9.3661 > 4.7374. (B) Do not reject Ho since 2.3415 4.7374. (C) Reject Ho since 8.1954 > 4.7374. (D) Reject Ho since 9.3661 > 6.5415. (E) Reject Ho since 6.2441 >4.7374. (F) Reject Ho since 8.1954 > 6.5415. (G) Do not reject Ho since 2.3415 6.5415. (H) Do not reject Ho since 6.2441 6.5415. Problem #1(c): Select conclusion Just Save Submit Problem #1 for Grading
