Eldrick manages wildlife samples for Ducks Unlimited. Two samples of duck populations at a migratory site are shown in the table below. Which statement about the samples is true?Duck Pond SamplesSample 1Sample 2Mallard21Mallard8Wood Duck4Wood Duck17Green Wing Teal9Green Wing Teal15American Widgeon6American Widgeon0

The two samples show large differences in the counts for several duck types: for example, Mallards number 21 in Sample 1 but 8 in Sample 2, while Wood Ducks number 4 and 17. That much variation suggests the samples may not give a reliable picture of the populations, so Eldrick should collect another sample rather than rely on just one or average these two.
