This is the same thing as two over 100. So two over 100 times one over 1.96 needs to be less than or equal to two over 196. Let me scroll down a little bit. This is fancier algebra than we typically do in statistics, or at least in introductory statistics class. All right, so let's see. We could take the reciprocal of both sides. We could say the square root of n over 0.5 and 1.96 over two.
