Question: The sample average in one sub-sample is \({{\bar{x}}_{a}}\) = 4.3 and the sample standard deviation is s a = 5.4. The sample average in the second subsample is \({{\bar{x}}_{b}}\) = 2.1 and the sample standard deviation is s b = 6.7. The size of the first sub-sample is n a = 83 and the size of the second sub-sample is n b = 92. We are interested in testing that the expectations in the associated sub-populations are equal to each other. The following 3 questions refer to the given information.
