\fHere is - o a data set concerningthree treatment groups: A, B, & C. In order to perform an ANOVA on the data to assess if A, B, and C are different, what assumptions must be met? Enter the number ofa_H correct answer choices in numerical order gparated by commas in the blank below. 1. The variance between the three groups must be equal. 2. The data in each group must be normally distributed. 3. The members of the sample populations were randomly chosen 4. The variance between each group must be unequal. 5. The variances of each group must overlap with the variance of at least one other group. Using the data analysis add in for Excel (installation instructions can be found here m EalMao (3)), perform a single factor ANOVA to deduce if A, B, and C are different.
