C) The standard deviations of both samples must be known the sample sizes are irrelevant) before the above question can be answered.
D) Both the standard deviations and sample sizes must be known before the above question can be answered.
E) Even if both the standard deviations and sample sizes were known, the above question cannot be answered.
