When is it appropriate to use the pooled two-sample t-methods? Choose the correct answer below. O A. Use the pooled two-sample t-methods when the distribution of the difference in sample means is known to be skewed. O B. Use the pooled two-sample t-methods when the population standard deviations are known. O C. Use the pooled two-sample t-methods when the samples come from populations with different standard deviations. D. Use the pooled two-sample t-methods when the samples come from different populations with the same, or nearly the same, standard deviations.
