Question is :

Given the following sample information, test the hypothesis that the treatment means are equal at the 0.10 significance level: Treatment 1 Treatment 2 Treatment 3 HWHUINW a. State the null hypothesis and the alternative hypothesis. Ho : H1 = H2 E H3 H1 : Treatment means are not all the same. b. What is the decision rule? (Round the final answer to 2 decimal places.) Reject Ho if F> 2.57 c. Compute SST, SSE, and SS total. (Round the final answers to 2 decimal places.)SST = 537.45 9 SSE = 53.00 0 55 total = 590.45 0 d. Complete the ANOVA table. [Round the 55.
