What can be concluded from this graph? Interval Plot of ALL_BATCHES vs FACTOR 95% CI for the Mean 120 100 80 80 ALL_BATCHES 60 60 40 20 20 0 1 2 3 4 FACTOR The pooled standard deviation is used to calculate the intervals. This graph was obtained from a CLASSICAL ONE-WAY ANOVA. You should APPLY the KRUSKAL- WALLIS nonparametric ONE-WAY ANOVA to a sample of size 7 from each of the four BATCHES to confirm what the graph suggests. To do this, you should apply equation 4 to your sample of size 7.
