3.1.1. t-Test and p-value
Since Fcalculated ≫ Fcritical, the null hypothesis H0 is rejected and the conclusion is that treatment means significantly differ; hence the membrane types significantly affect the mean permeate flux for the MgCl2/water system at a salt concentration of 4.76 g/L. The p-value at the specified level of α is extremely small, signifying highly significant differences of means (Table 3).
