Parallel design, create a randomized list for a study, with block factor of 2, control and active, total 100 patients. (post the SAS or R code)
If there is interest in testing the significance of the blocking factor in a randomized block ANOVA design, what should you do?
Data from a randomized block design are shown in the following table. Treatment Levels 2 3 4 10 7 9 5 Block 1 8 Block 2 6 6 Block 3 7 The Error Sum of Squares (SSE) is_ ○ 4.67 012 ○ 2.33 ○ 28.67 O 11
3.38 A single-factor completely randomized design has four levels of the factor. There are three replicates and the total sum of squares is 330.56. The treatment sum of squares is 250.65. (a) What is the estimate of the error variance σ (b) What proportion of the variability in the response vari- able is explained by the treatment effect?
1-A randomized block design ANOVA has five treatments and four blocks. The computed test statistic (value of F) is 4.35. With a 0.05 significance level, the appropriate table value and conclusion will be?2-A randomized block experiment having five treatments and six blocks produced the following values: SSTR = 287, SST = 1,446, SSE = 180. The value of SSB must be? Thank you

An experiment employing a randomized block design has 4 treatments and nine blocks, for a total of 4x9=36 observations. Conduct a test at alpha 0.05 to verify whether the block means are equal, knowing that SSTO = 500, SST = 50% of the total Sum of Squares and SSB is = 20% of SSTO. The results of the analysis for block effect are: O F = 2; Rejection region F =2.36 Fail to reject Ho, There is no block effect...

Create a 32-run crossed array design with six control factors and two noise factors such that (1) all control × noise two-factor interactions are clear, (2) all noise main effects are clear, and (3) all noise × noise two-factor interactions are clear. Fully describe the reasoning that you used to create your design.
