The approximate percentage of kangaroos in Queensland Australia are shown by type in the following table The percentage of red are 60% and the percentage of euro are 40%. Based on this information which sample of 50 kangaroos best represents the entire population of kangaroos in Queensland Australia?

Answer 1

It would be best to have a sample that reflects the same distribution of kangaroo types as the overall population of Queensland. Therefore, a sample of 30 kangaroos that are red kangaroos and 20 kangaroos that are euro kangaroos would be the most representative of the entire population of kangaroos in Queensland Australia.
