A researcher is testing which animal performs better on the anxiety task that involves a stranger walking into the room. In one group they test dogs and another cats and see how long it takes the animal to approach the person “stranger”. Here is the data from 10 subjects that was recorded in seconds:Dogs: 120, 126, 140, 115, 112, 130, 125, 108, 128, 143Cats: 125, 140, 128, 133, 138, 129, 135, 129, 140, 125Which set of scores has a lower SEM? You should be able to do this just by looking at the raw scores, but of course you can do the math if it helps you answer the question.
