Quizplus · Accepted Answer

The appropriate null hypothesis when testing whether two population variances are equal is that they are equal, so the null hypothesis should be represented as H0: σ12 = σ22. Option A is the only one that represents this null hypothesis correctly. Option B represents the alternative hypothesis, which is that the variances are not equal. Options C and D represent one-tailed hypotheses, which are not appropriate for testing equal variances.
