In order to determine the test statistic, we need the sample means, sample standard deviations, and sample sizes. However, this information is not provided. Additionally, the question does not specify whether the sample sizes are equal or unequal, which would affect the choice of test statistic. Therefore, without more information, we cannot determine the test statistic.
