As part of his work for nasa, dr. murdock was asked to find out what percentage of people in the continental united states saw haley's comet when it was last visible. he randomly selected three major cities, seattle, cleveland, and boston, and polled 1000 randomly selected people from these cities. he finds that fewer than 5% of the people he interviewed saw the comet, so he concludes that fewer than 5% of people in the continental united states saw the comet. is murdock using a generalization or an analogy?
