Explanation:

Step1: Find sum - of - squares among treatments

We know that $SS_{total}=SS_{among\ treatments}+SS_{error}$. So, $SS_{among\ treatments}=SS_{total}-SS_{error}$.
$SS_{among\ treatments}=6479.32 - 3044.86=3434.46$

Step2: Calculate mean square among treatments

The formula for the mean square among treatments $MS_{among\ treatments}=\frac{SS_{among\ treatments}}{DF_{among\ treatments}}$. Given $DF_{among\ treatments} = 3$.
$MS_{among\ treatments}=\frac{3434.46}{3}=1144.82$

Answer:

$1144.82$
