WebJun 27, 2015 · If T is a random variable with that distribution then the P-value p is P ( T > t). That is, 1 − p = P ( T ≤ t). The value t you wish to reclaim from the reported p is then the inverse CDF (quantile) function of 1 − p . For example, if n = 16, and p = 0.037, then we could use statistical software to obtain t = 1.92. WebAs such, don’t just buy a cart from the first source you find.
