And we figure out that it is 22 out of the 200 people in the sample are unemployed. So this is 0.11. Now the next step is, assuming the null hypothesis is true, what is the probability of getting a result this far away or further from the assumed population proportion? And if that probability is lower than alpha, then we would reject the null hypothesis, which would suggest the alternative. But how do you figure out this probability? Well, one way to think about it is we could say how many standard deviations away from the true proportion, the assumed proportion, is it? And then we could say, what's the probability of getting that many standard deviations or further from the true proportion?
