Which explains whether or not this is a representative sample?
Yes, this is a representative sample because each type of weed is represented in the sample.
Yes, this is a representative sample because each type of weed is represented approximately the same number of
times in the sample.
No, this is not a representative sample because each type of weed should be represented in proportion to the number
of weeds actually present in the yard.
No, this is not a representative sample because each type of weed should be represented exactly the same number of
