Question
Please only solve question 3. Thank you
An experiment was conducted using a randomized block design with one factor. The data from the experiment are displayed in the following table Block Treatment (25 points) Create the ANOVA table by hand, given that SST = 21.5555, SSTO = 30.2222 and CM-266.7778. The easier computation formulas are on page F-10 in the formula packet I. 2, (25 points) Perform a hypothesis test with = .05 to determine if the treatment has a significant effect on the mean response. Give the hypotheses, test statistic, critical value, conclusion, and interpretation. 3. (25 points) Is it necessary to compare treatment level means? Why or why not? (25 points) Was it helpful to use the blocking factor? Give the test statistic and the critical value, using = .05, to justify your answer 4.Explanation / Answer
3) Yes it is necessary to compare treatment levels means because each treatment is appearing in the each block, so every treatment will appear in all the blocks. So each treatment can be considered as if replicated the number of times as the number of blocks. Thus in RBD, the number of blocks and the number of replications are same. Therefore if we want to conduct the expereminet it is necessary to compare treatment means.
I hope answer will help you. Thank you!
