Yes, because they are large samples, it cannot be assumed that the distributions of the sample means are approximately normal. YC. No, because they are large samples, it can be assumed that the distributions of the sample means are approximately normal. O D. Yes, because the samples are not large enough to assume normality. (e) Use the one-way ANOVA procedure with a = 0.05 to determine if the mean behaviour scores are different for the three treatment groups. What are the null and alternative hypotheses being tested? - X Summary of the results O A. Ho Pc <PR <HH and H, Hcz UR HH O B. Hg Pc + HR +UH and H Pc =PR = H Sample mean Sample variance n C.
