Sample Consider the data in the table collected from four independent populations. The conclusion of a one-way ANOVA test using a=0.05 is that the population means are not all the same. Determine which means are different using a = 0.05. Sample 1 5 6 3 8 Sample 2 12 14 16 Bokea 21 13 15 24 Sample 4 10 3 11 Click here to view the ANOVA summary table.
