Put simply, if you’re above 50%, you’re a “pass” (which means a 3). But 50% right on the nose could be a “2”. A "2" is usually not accepted by universities unless there are extenuating circumstances. A "1" is a fail.

FRQ Practice Submission 2. a) The population is approximately normal, the value of n (40) is >= 30 by the Central Limit Theorem, and the sample shows no strong skew or outliers. The center of the sample mean is 210 seconds. The variability is 10.752 seconds because 68/sqrt (40) = 10.752.Thus, the z-score for a woman who is 62 inches tall is -1.2. (5) Plugging in the values, we get: z = (3.0 - 2.5) / 0.4 = 0.5 / 0.4 = 1.25. Thus, the z-score for a student at College B who has a GPA of 3.0 is 1.25.
