The assumption that the distribution of the underlying population is bimodal is not specific to hypothesis testing with the z test. In fact, such an assumption would be rare in most hypothesis testing situations. The other assumptions listed (scale measure for dependent variable, random participant selection, and approximate normality of population distribution) are all commonly assumed in hypothesis testing, specifically for the z test.
