question 2 of 4, step 3 of 4
step 3 of 4: find the mean square for treatments, mst. round your answer to four decimal places.
sst ≈ 13.1818
sse ≈ 812.5455
answer

Explanation:

Step1: Recall the formula for MST

The formula for the mean - square for treatments (MST) is $MST=\frac{SST}{df_{treatment}}$. However, we are not given the degrees of freedom for treatments ($df_{treatment}$) directly. But assuming a one - way ANOVA setup with $k$ groups and $n$ total observations, if we assume $k$ is the number of columns in the data table (here $k = 4$) and $n$ is the total number of data points ($n=44$), then $df_{treatment}=k - 1=4 - 1 = 3$.

Step2: Calculate MST

We know that $SST\approx13.1818$ and $df_{treatment}=3$. Using the formula $MST=\frac{SST}{df_{treatment}}$, we substitute the values: $MST=\frac{13.1818}{3}$.
$MST\approx4.3939$

Answer:

$4.3939$
