So going back to this right over here, if our z is equal to 1.88, so this is equal to 1.88, then all of this area, up to and including 1.88 standard deviations above the mean, that would be 97%. But if you were to go 1.88 standard deviations above the mean and 1.88 standard deviations below the mean, that would leave 3% open on either side. And so this would be 94%. So this would be 94%. But to answer their question, what critical value z star? Well, this is going to be 1.88. And we're done.
