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. The scientists collect a
random sample of 30 adult pythons and measure their lengths. In their sample the mean
length was 19.5 feet long. 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?
Explain.
