So that would be 0.11 minus 0.08 divided by the standard deviation of the sampling distribution of the sample proportions. And we can figure that out. Remember, all that is is, and sometimes we say, well, we don't know what the population proportion is. But here we're assuming a population proportion. So we're assuming it is 0.08. And then we'll multiply that times one minus 0.08. So we'll multiply that times 0.92.
