Question

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 samples sample 1 sample 2 mallard 21 mallard 8 wood duck 4 wood duck 17 green wing teal 9 green wing teal 15 american widgeon 6 american widgeon 0 eldrick can use both of these samples to find the mean frequency of each duck. eldrick should take another sample because there is too much variability in the two samples. eldrick should use only the first sample to find the mean frequency of each duck. eldrick should use only the second sample to find the mean frequency of each duck.

Explanation:

Step1: Recall sampling requirements

For accurate mean - frequency calculations, samples should be representative and consistent.

Step2: Analyze the given samples

The frequencies of different duck species in Sample 1 and Sample 2 vary greatly (e.g., Mallard has 21 in Sample 1 and 8 in Sample 2; Wood Duck has 4 in Sample 1 and 17 in Sample 2). This large variability indicates that the samples may not be reliable for calculating a single mean frequency for each duck species.

Answer:

Eldrick should take another sample because there is too much variability in the two samples.
