If the null hypothesis is false, the between-groups estimate of population variance will not give an accurate estimate of the variation within the populations because it also will be affected by:
A)the difference between the variances of the two distributions of means
B)the sum of the variances of the two distributions of means
C)the difference between the two estimated population variances
D)the variation among the populations

If the null hypothesis is false, there is likely variation among the populations. The between-groups estimate of population variance will not give an accurate estimate of the variation within the populations because it does not take this variation among the populations into account.
