A plant physiologist investigated the effect of flooding on rootmetabolism in two tree
species: flood-tolerant river birch and the intolerant Europeanbirch. Four seedlings of
each species were flooded for one day, and four were used ascontrols. The concentration
of adenosine triphosphate (ATP) in the roots of each plant wasmeasured. The data (nmol
ATP per mg tissue) as shown in the table.

| 1.45 | 1.70 | 0.21 | 1.34 |

| Mean | 1.19 | 1.785 | 0.2925 | 1.20 |
For these data, SS(species of birch)=2.19781,SS(flooding)=2.25751, SS(interaction)=0.097656,
and SS(within)=0.47438.
i. Construct the ANOVA table, include p-values.
iii. What is the F test statistic and its degrees of freedom fortesting that species has no
effect on ATP concentration?
