Many Organized Groups Publish a Newsletter and the Catchier the Name

Many organized groups publish a newsletter and the catchier the name, the better. These newsletters differ in quality from month to month and also from organization to organization. Newsletters from the following organizations were rated on a scale that ranged from 1 (poor) to 20 (excellent). Perform an ANOVA on the scores and put your calculations into a summary table. Compare the two newsletters with the best and the worst average with a Tukey HSD and an effect size index. Write an interpretation of the data and your analyses. $$\begin{array} {cc c } \begin{array} { c } \text { Wildebeast Society } \\\text { "Gnusletter" }\end{array} & \begin{array} { c } \text { Executioner's Society } \\\text { "Nooseletter" }\end{array} & \begin{array} { c } \text { Reason and Common Sense } \\\text { Society "Nousletter" }\end{array} \\\hline 18 & 7 & 10 \\14 & 11 & 12 \\13 & 8 & 13 \\& 6 & 10\end{array}$$
