So it's 0.037. So we figured out the standard deviation here of the distribution of our sample proportions is going to be, let me write this down, I'll scroll over to the right a little bit. It is 0.037. I think I'm falling off the screen a little bit. So we'll just say 0.037. Now, to figure out the probability of having a sample proportion of 0.38, we just have to figure out how many standard deviations that is away from our mean, or essentially calculate a z statistic for our sample, because a z statistic or a z score is really just how many standard deviations you are away from the mean, and then figure out whether the probability of getting that z statistic is more or less than 5%. So let's figure out how many standard deviations we are away from the mean.
