WebA continuous random variable Z is said to be a standard normal (standard Gaussian) random variable, shown as Z ∼ N(0, 1), if its PDF is given by fZ(z) = 1 √2πexp{− z2 2 }, … WebThe grade is 65. Well first, you must see how far away the grade, 65 is from the mean. So 65 will be negative because its less than the mean. 65-81 is -16. Divide that by the standard deviation, which is 6.3. So -16 divided by 6.3 is -2.54, which is the z score or "the standard deviation away from the mean.
