Monique can use both samples to find the mean frequency of each duck.
Monique should take another sample because there is too much variability in the two samples.
Monique should use only the first sample to find the mean frequency of each duck.
Monique should use only the second sample to find the mean frequency of each duck.

Answer 1

Monique can use both samples to find the mean frequency of each duck.

answer: A.

Answer 2

The correct answer is: Monique can use both samples to find the mean frequency of each duck. Since the variability (or by how much the data differs from the mean and from each other) is only little, Monique can use the two samples to compute for the mean frequency of each species.
