For an analysis of variance, if the between-group estimate of the population variance is 30, and the within-group estimate is 25, then the f ratio

1.2

Step-by-step 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

So for the given variance F ratio will be 1.2
