The relevant summary statistics show the sample means and sample standard deviations of two different groups, indicating that the samples are independent and taken from normally distributed populations. Option A is incorrect because the question does not provide any information about normality assumption, and it is not necessary for conducting a hypothesis test. Option B is incorrect because the question states that the samples are independent. Option C is incorrect because the difference of the sample variances is not used to test the hypotheses, but rather the difference of the sample means.
