The statement indicates that there are two samples, and that they are independent. However, there is no information provided about the shape of the population from which the samples are drawn. Therefore, the assumption is that the samples are taken from a normal population, which is necessary for conducting a hypothesis test. The difference of the sample variances is not used to test the hypotheses.
