2. Herpetologists (snake specialists) found that a certain species of reticulated python have an average length of 20.5 feet with a standard deviation of 2.3 feet.

One of the herpetologists fears that pollution might be affecting the natural growth of the pythons. Do you think this sample result is unusually small?
