The fuzzy p-value is viewed as a representation of a certain second-order possibility measure. According to Walley, any second-order possibility measure can be converted into a pair of lower and upper probabilities. Thus, we can convert the fuzzy p-value into an interval in the real line. We derive a construction of imprecise (but non fuzzy) tests, which are formally similar to recent tests used to manage with set-valued data.}, isbn = {978-3-540-85027-4}, author = {Couso, In{\'e}s and S{\'a}nchez, Luciano}, editor = {Dubois, Didier and Lubiano, M.
