Select all of the following that are true about one way anova when there are m groups. The null hypothesis is that all of the means are the same The alternative hypothesis is that exactly one mean is different If we conducted separate tests instead of using anova we would have to do m tests. The underlying random variables are normally distributed It is assumed that the variance is the same for each group/category Select all of the following that are true about one way anova when there are m groups and n total observed values. the total sum of sq the test statistic follows an F distribution O the degrees of freedom for the reference table lookup is (n-1, n-m) O the rejection rule is that we reject the null hypothesis if the test statistic is smaller than the value we look up in the reference table in general we present the ANOVA results in a table
