The weights, in pounds, of the cats in an animal adoption center are normally distributed. If a random sample of cats is taken and the confidence interval is (7.9,12.7), what is the margin of error?

Give just a number for your answer. For example, if you found that the margin of error was 2, you would enter 2.
