![But wait, how did we decide on the width of that interval? We again started in the middle, with the sample
proportion. There's a different formula for the margin of error for sample proportions:
p(1 - p)
MOE = z
n
This formula consists of three values: p is the sample proportion, n is the sample size, and z is a
multiplier that we choose based on the confidence level we need.
We use the same values for z* as before:
