And so let me just assume that, and then let me calculate n. So let me set up an inequality here. We want 1.96, that's our critical value, times the square root of, we're just going to assume 0.5 for our sample proportion, although, of course, we don't know what it is yet until we actually take the sample. So that's our sample proportion. That's one minus our sample proportion. All of that over n needs to be less than or equal to 2%. We don't want our margin of error to be any larger than 2%. And let me just write this as a decimal, 0.02.
