Now, in that situation, what is going to be our critical region here? Well, we need a result, so we need some critical z-value here, some critical z-score, or some critical, I should actually say some critical value here, because this isn't a normalized standard. This isn't a normalized normal distribution. But so there's some critical value here. The hardest thing in statistics is getting the wording right. There's some critical value here that the probability of getting a sample from this distribution above that value is only 5%. So we just need to figure out what this critical value is.
