Answer:
The conclusion that cuckolder are able to discriminate kin from non kin
Explanation:
From the above question, researchers carried out tests on the two types of fish (males cuckolder and parental males) to see if they can identify kin and non kin from the offsprings, using a null test.
But the test for cuckolder was rejected by the researchers for the cuckolder so they can't say cuckolder can indentify between kins and non kins, they didn't pass the test so it should be concluded that cuckolder can't identify between kin and non kin, instead of concluding they can identify them, that is the wrong conclusion.
Answer:
The conclusion is apt and correct.
Explanation:
The original null hypothesis for a 2-sample t-test is that the two groups are equal.
Its said above that the researcher used a two-sample method to test the null hypothesis.
Objective - to test whether offspring from the two types of eggs (fertilized by parental male vs. fertilized by cuckolder male) are able to distinguish kin (siblings) from non-kin using odor cues.
H° - null hypothesis that fish are unable to discriminate between kin and non-kin.
Action point.
1. H° was accepted for offspring of
parental males.
2. H° was rejected for offspring from cuckolder males
Conclusion:
Offspring of cuckolder males are more able to discriminate kin from non-kin than are offspring of parental males.
The conclusion is apt and correct.
