Answer #1

Assumptions for conducting an analysis of variance test or ANOVA includes the following

(A) Common variance

(B) Independence

(C) Normally distributed

Common variance means that the different samples must have same or common population variance in order to apply ANOVA for testing purpose

so, option A is only correct answer

We only same need equal variance, but not requiredment for ANOVA includes a maximum standard deviation of 100 or largest sample standard deviation is no more than twice the smallest

So, option B and C are incorrect

Suppose that the overall F-test obtained from performing a one-way ANOVA resulted in a p-value that was not statistically significant. Which of the following CANNOT be true? The variability within the groups is very large compared to between-group variability. The variability between the groups is very large compared to within-group variability. The ratio of the between and within variability was not sufficiently large. The F-statistic was not larger than the critical value obtained from the F-distribution.
