Question

A scientist is studying tulips and daffodils. The scientist estimates that there are 150 tulips in the population of 600 tulips and daffodils. He chooses flowers from random parts of the garden to study. Which best explains how he can choose a random sample of flowers to represent the population?

Answer 1

Answer:

He can choose random sample of tulip and daffodils by following the ratio:

tulip: dafodils = 1 : 3

Step-by-step explanation:

150 tulips means 600 - 150 = 450 daffodils

If we take ratio of tulips to daffodils:

tulip: daffodils: 150 : 450 it becomes 1 : 3

So the scientist can choose random sample according to this ratio:

If he takes 10 tulips he would have to take 30 daffodils

if he takes 15 tulips he would have to take 14 daffodils

           

Answer 2

He can choose 10 tulips and 30 daffodils.
