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}.
