Answer:
1.2
Explanation:
We have given the variance between - group estimate is = 30
And the variance within - group estimate is =25
Now we have to calculate the F ratio
F ratio is defined as the ratio of variance between the group and variance within the group
So F ratio
![=(30)/(25)=1.2](https://img.qammunity.org/2020/formulas/mathematics/high-school/krzlayagew3sgd1q07tj79wylk5va1crtw.png)
So for the given variance F ratio will be 1.2
