Question

monique 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 17 mallard 21 wood duck 8 wood duck 7 green wing teal 10 green wing teal 8 american widgeon 5 american widgeon 6 monique can use both samples to find the mean frequency of each duck. monique should take another sample because there is too much variability in the two samples. monique should use only the first sample to find the mean frequency of each duck. monique should use only the second sample to find the mean frequency of each duck.

Explanation:

Step1: Recall sampling principles

To estimate population - related statistics like the mean frequency, having multiple samples is beneficial as it reduces sampling error.

Step2: Analyze the options

• Option 1: Using both samples to find the mean frequency of each duck is a good approach as it combines information from different subsets of the population, which gives a more accurate estimate of the true population mean frequency.
• Option 2: While there is some variability between the two samples, it is not necessarily so large that another sample is required immediately.
• Option 3: Using only the first sample would discard valuable information from the second sample.
• Option 4: Using only the second sample would discard valuable information from the first sample.

Answer:

Monique can use both samples to find the mean frequency of each duck.
