not sure what test is best

There are two genetically distinct types of Gouldian nches. One has a red face, and the other has a black face. Previous experiments have shown that female nches have a strong preference for mating with males with the same face color as themselves, and that when different face tvpes of nch mate with one another, their offspring are less likely:I to survive. Researchers paired females sequentiallv with maies of both types in random order. Each time, females produced a 'orood of voung with the assigned male. For each pairing, blood corticosterone concentration was measured as an index of the amount of stress the females experienced.
