A marine biologist is examining the effects of oil pollution on a population of birds known as seagulls (Larus canus). She is pa

rticularly concerned that oil pollution may reduce the number of eggs raised in a seagull nest. During one breeding season, she counted the number of eggs present in a sampling of six seagull nests near each of the 14 refineries throughout the state. She discovered that seagulls laid and raised an average of four eggs per season. To confirm her hypothesis, the researcher must now examine seagull nests that have not been exposed to oil pollution. The researcher believes she is correct, and so expects to find A) 0-2 eggs per nest. B) 2-4 eggs per nest. C) 1 egg per nest. D) 4-6 eggs per nest.
