Answer:
Cluster Sampling
Step-by-step explanation:
In cluster sampling, the population is divided into several categories and random sampling is applied to the selected clusters.
This method is used when the population is not homogeneous and therefore has to be divided into several clusters.
This sampling method is prone to <em>sampling error</em> because it leaves some clusters out. On the other hand it is <em>easier</em> to implement.

Answer:
Start: Brown feather % is 97% Grey feather % is 3%
End: Brown feather % is 19% Grey feather % is 81%
Step-by-step explanation:
Start:
There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7
divide each number by 7(679/7 and 21/7)
and you get 97 and 3 which will be your percentages
End:
There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4
divide each number by 7.7(140/7.4 and 600/7.4)
and you get about 19(rounded) and about 81(rounded) which will be your percentages
Hope this helps!!!
