Answer
A
Rhonda needs to continue taking samples of ducks until both samples have at least one of each type of duck.
B
Rhonda should take a third sample and then use the two that are most representative since these samples vary quite a bit.
C
Rhonda should use both of these samples as they are to make inferences about the average population of each type of duck in the pond.
D
Both samples must be biased because there are more Mallards than any other type of duck recorded in the sample.
