It's actually going to be p hat is 0.5. And I wanna emphasize, we don't know. She didn't even perform the sample yet. She didn't even take the random sample and calculate the sample proportion. But we wanna figure out what n to take. And so to be safe, she says, okay, well, what sample proportion would maximize my margin of error? And so let me just assume that, and then let me calculate n. So let me set up an inequality here.
