Ghost of Speciation Past. In the article, "Ghost of Speciation Past" (Nature, Vol. 435, pp. 29-31), T. Kocher looked at the origins of a diverse flock of cichlid fishes in the lakes of southeast Africa. Suppose that you wanted to select a sample from the hundreds of species of cichlid fishes that live in the lakes of southeast Africa. If you took a simple random sample from the species of each lake and combined all the simple random samples into one sample, which type of sampling design would you have used? Explain your answer.

The given statement is:

In the article, "Ghost of Speciation Past", T. Kocher looked at the origins of a diverse flock of cichlid fishes in the lakes of southeast Africa.

Suppose that you wanted to select a sample from the hundreds of species of cichlid fishes that live in the lakes of southeast Africa. If you took a simple random sample from the species of each lake and combined all the simple random samples into one sample

From the given study the information that we have gained is that a sample was chosen from among the hundreds of species of cichlid fish found in Southeast lakes, and after that, a simple random sample was collected from each lake's species.

Then the researcher combined all the simple random samples into one sample.

Therefore, the stratified sample design would be ideal in this circumstance.
