Class TTestResult
The result of statistical T test is stored in this class. If the T value is closer to 0.0 than TCriticalValueTwoTail or even TCriticalValueOneTail, then we can't deduce that D(hypothesized difference) is not good mean value difference. In other case ( TCriticalValueTwoTail is closer to 0.0 than TValue), there is a huge probability that hypothesized difference D hadn't been chosen correctly.
