Z = atomic number = number of protons in the nucleus = number of electrons orbiting the nucleus; A = mass number = number of protons and neutrons in the most common ... The z-score is the number of standard deviations between the given value and the mean. If its value is above the mean, then the z-score is positive, and if it lies below the mean, the value of the z-score is negative. Z-scores standardize normal distributions, which allows analysts to measure the scoring probability within the normal distribution.Z test is a statistical test that is conducted on data that approximately follows a normal distribution. The z test can be performed on one sample, two samples, or on proportions for hypothesis testing. It checks if the means of two large samples are different or not when the population variance is known.This gives the remaining 3 solutions which are the third roots of unity. Let z = reiθ z = r e i θ. Then we need r2ei2θ = re−iθ r 2 e i 2 θ = r e − i θ. We at least require that their magnitudes be the same, so r = 0 r = 0 or r = 1 r = 1.
