The difference between the two was 0.051. So what we can do is figure out what's the probability, assuming that the true proportions are equal, that the mean of the sampling distribution of this statistic is actually 0, what's the probability that we get a difference of 0.051? So what's the likelihood that we get something that extreme? And what we're going to do here is just figure out a z score for this, essentially figure out how many standard deviations away from the mean this is. That would be our z score. And then figure out, is the likelihood of getting a standard deviation or that extreme of a result or that many standard deviations away from the mean, is that likelihood more or less than 5%? If it is less than 5%, we're going to reject the null hypothesis.
