Explanation:

Step1: Recall the relationship between sums of squares

The total sum of squares (SS Total) is the sum of the sum of squares among treatments (SS Among Treatments) and the sum of squares of error (SS Error). That is, $SS_{Total}=SS_{Among Treatments}+SS_{Error}$.

Step2: Rearrange the formula to find SS Among Treatments

We can rewrite the formula as $SS_{Among Treatments}=SS_{Total}-SS_{Error}$.

Step3: Substitute the given values

Given $SS_{Total} = 6479.32$ and $SS_{Error}=3044.86$. Then $SS_{Among Treatments}=6479.32 - 3044.86$.
$SS_{Among Treatments}=3434.46$

Answer:

$3434.46$
