You may need to use the appropriate appendix table or technology to answer this question. In a completely randomized experimental design, 11 experimental units were used for each of the 3 treatments. Part of the ANOVA table is shown below. (a) Fill in all the blanks in the ANOVA table. Source of Variation Sum of Squares Degrees of Freedom Mean Square F Between Treatments 1,496 Within Treatments (Error) Total 4,796 (b) At a 0.05 level, test to determine whether or not the means of the three populations are equal. State the null and alternative hypotheses. Ho: M = M₂ = M3 H. = P2 = 13 O Ho: At least two of the population treatment means are different. Ha: My = I 2 = uz O Holly = uz = 3 Haily * \z uz Ho: \q = H2 = 43 Ha: At least two of the population treatment means are different. O Ho: M, * uz 7 43 H : At least two of the population treatment means are different. a

Find the value of the test statistic. Find the critical value corresponding to a level a = 0.05 test to see if there is a significant difference among the treatment means. (Round your answer to two decimal places.) What conclusions can we draw? O We should not reject H, and therefore we cannot conclude there is a significant difference among the mean response of the three treatments. o We should reject Ho and therefore we can conclude there is a significant difference among the mean response of the three treatments. O We should not reject H, and therefore we can conclude there is a significant difference among the mean response of the three treatments. We should reject He and therefore we cannot conclude there is a significant difference among the mean response of the three treatments.
