Quizplus · Accepted Answer

The value of the test statistic for the pooled two-sample t-test is calculated based on the difference between the sample means, the pooled standard deviation, and the sizes of the samples involved. Without specific data, it's impossible to calculate or confirm the exact value from the options given. However, if B (2.79) is identified as the correct answer, it suggests that in the context of the question (which is not provided here), the calculations or the scenario described leads to 2.79 being the value of the test statistic. This value is used to determine if there is a significant difference between the two groups being compared.
