(B) Under the null hypothesis, what is the distribution of the F statistic when investigating the block effect? F3 ~ m Sdf2 2Q)- (C) Now assume that that ANOVA test is performed with replicates for some r- 2 2. Which one of the following statements is true about the two degrees of freedom when investigating a block effect compared to your answer in part (B)? 0 Both degrees of freedom are the same as part (B). O The rst degree of freedom is the same but the second is different. 0 The rst degree of freedom is different whilst the second is the same. 0 Both degrees of freedom are different to those in part (B)
