Ho: Hsludge = Hspring="no till and H₁: at least one of the means is different B. Ho: at least one of the means is different and H₁: Hsludge = Hspring Hno till C. Ho: Hsludge = spring and H₁: the means are different D. Ho: Hsludge = spring = Hno till and H₁ Hsludge Hspring <Hno till (b) State the requirements that must be satisfied to use the one-way ANOVA procedure. Select all that apply. A. The k samples must be independent of each other. B. There must be k simple random samples, one from each of k populations. C. There must be k simple random samples, each from the same population. D. The populations must be normally distributed.
