Question
Null: A population of birds will mate randomly with their own wing color type.
Alternative hypothesis: A population of birds are preferentially mating with their own wing color type.
Choose all answers correctly identify problems with the hypothesis pair.
Select one or more:
a. Birds randomly mating would not mate only with their own wing color.
b. The null hypothesis includes non-random mating.
c. The null and alternative hypothesis are switched
d. Birds may choose to mate with birds of a the differing wing color. This is not included in the null hypothesis.
e. Birds may choose to mate with birds of a the differing wing color. This is not included in the alternative hypothesis.
Explanation / Answer
Answer) In this case, we have two hypothesis; null hypothesis and alternate hypothesis.
null hypothesis depicts a random mating, while alternate hypothesis depicts non-random (preferential) mating. as we know that a non-random mating means the mating behavior between two individuals of specific character. while random mating is mating behavior between individuals with no specfic preference. therefore, null hypothesis has a problem; random mating means mating with individuals of a different color without any preference.
therefore, these are the problems with the null hypothesis, in this case;
a. Birds randomly mating would not mate only with their own wing color.
b. The null hypothesis includes non-random mating.
d. Birds may choose to mate with birds of a differing wing color. This is not included in the null hypothesis.
