- TTestPaired( <List of Sample Data 1>, <List of Sample Data 2>, <Tail> )
- Performs a paired t-test using the given lists of paired sample data.
*Tail*has possible values "<", ">" , "≠" that determine the following alternative hypotheses:- "<" = μ < 0
- ">" = μ > 0
- "≠" = μ ≠ 0
- ( μ is the mean paired difference of the population)

- Results are returned in list form as
*{Probabilty value, t-test statistic}*. **Example:**`TTestPaired({1, 2, 3, 4, 5}, {1, 1, 3, 5, 5}, "<")`

yields*{0.5, 0}*.
