When to use z or t statistics in significance tests

when n (sample size) is greater or equal to 30, can we use use z statistics because the sampling distribution of the sample mean is approximately normal, right? if this is the case, then why does t table contain rows where the degree of freedom is 100, 1000 etc …

Z-test: Definition, formula, examples, uses, z-test vs t-test

Like t-tests, z tests are also based on normal probability distribution. Z-test is the most commonly used statistical tool in research methodology, with it being used for studies where the sample size is large (n>30). In the case of the z-test, the variance is usually known. Z-test is more convenient than t-test as the critical value at each ...


3.5: Möbius Transformations: A Closer Look

Suppose T(z) = (az + b) / (cz + d) is a Möbius transformation that fixes 0 and ∞. In this case, the form of the Möbius transformation can be simplified. In particular, since T(0) = 0, it follows that b = 0. And since T(∞) = ∞, it follows that c = 0. Thus, T(z) = a dz which may be written as. T(z) = reiθz.

T-Score vs. Z-Score: What's the Difference?

T-Score vs. Z-Score: T-score. Like z-scores, t-scores are also a conversion of individual scores into a standard form. However, t-scores are used when you don't know the population standard deviation; You make an estimate by using your sample. T = (X – μ) / [ s/√ (n) ]. Where: s is the standard deviation of the sample.

Complex Conjugates | Brilliant Math & Science Wiki

Complex Conjugates - Arithmetic. Given a complex number z = a + bi, (a, b in mathbb {R}) z = a+bi(a,b∈ R), the complex conjugate of z, z, denoted overline {z}, z, is the complex number overline {z} = a - bi z = a−bi. The complex conjugate has the same real component a a, but has opposite sign for the imaginary component b b.

Let now z belong to the circle jz 1j = r (any circle with center ̸= 0 may be mapped to this one by rotation and dilation) and w = 1 z.Then x 2 + y2 2x = r2 1, thus 2Rew + (r2 1)ww = 1.If r2 = 1 then Rew = 1 2, thus w belongs to a line. Otherwise, as 2Rew = w+ w, we get w + 1 r2 1 2 = 1 r2 1 1 (r2 1)2r2 (r2 1)2which is a circle centered at 1 r2 1, radius r=j(r2 1)j. The …
