Explanation / Answer

One-way ANOVA: 1, 2, 3, 4, 5

Source DF SS MS F P
Factor 4 344.66 86.17 30.63 0.000
Error 25 70.33 2.81
Total 29 414.99

S = 1.677 R-Sq = 83.05% R-Sq(adj) = 80.34%

Individual 95% CIs For Mean Based on Pooled StDev
Level N Mean StDev -+---------+---------+---------+--------
1 5 22.320 1.052 (----*-----)
2 7 27.743 1.643 (---*----)
3 7 30.957 2.249 (---*----)
4 5 29.500 1.259 (----*----)
5 6 23.117 1.614 (----*----)
-+---------+---------+---------+--------
21.0 24.0 27.0 30.0

Pooled StDev = 1.677
