WebThe null hypothesis is a default assumption (that a parameter has a certain value, two populations are the same, or a treatment has no effect). The alternative hypothesis assumes otherwise (that a parameter does not equal a certain value, two populations are different, or a treatment has an effect). WebThe null hypothesis assumes that the true mean difference between the paired samples is zero. Under this model, all observable differences are explained by random variation. Conversely, the alternative hypothesis assumes that the true mean difference between the paired samples is not equal to zero.
