a. The classical test statistic for the hypothesis 0 : μ = μ0 is the following:
For fuzzy data x1*,…, xn*, using the extension principle the characterizing function ξt*(·) of the fuzzy value of the test statistic can be obtained. Based on the support of t* the p-value is determined.
b. In order to construct the characterizing function of the fuzzy p-value p* a suitable number of δ-values is chosen and the corresponding δ-cuts of p* are calculated.
c. This is done as described before Proposition 13.1.
