Do lure colors influence Pacific halibut's desire to take the bait? To find out researchers selected 750 Pacific halibut

the other half were assigned to one with a neutral tone and no sparkle. On average, the halibut were more attracted
to the sparkly, bright colors. Which of the following is the largest population to which the results of this survey should
be generalized?
