Answers without enough detail may be edited or deleted. z* means the critical value of z to provide region of rejection if confidence level is 99%, z* = 2.576 if confidence level is 95%, z* = 1.960 if confidence level is 90%, z* = 1. ...Either ˉz or z∗ denotes the complex conjugate of z. The complex conjugate has the same real part as z and the imaginary part with the opposite sign. That means, if z = a + ib is a complex number, then z∗ = a − ib will be its conjugate. In the polar form of a complex number, the conjugate of re^iθ is given by re^−iθ. Free math problem solver answers your algebra homework questions with step-by-step explanations.

The negation of set membership is denoted by the symbol "∉". Writing {\displaystyle x\notin A} …Here's the formula for calculating a z-score: z = data point − mean standard deviation. Here's the same formula written with symbols: z = x − μ σ. Here are some important facts about z-scores: A positive z-score says the data point is above average. A negative z-score says the data point is below average. A z-score close to 0.

Basically, the definition states that “it is a collection of elements”. These elements could be numbers, alphabets, variables, etc. The notation and symbols for sets are based on the operations performed on them, such as the intersection of sets, the union of sets, the difference of sets, etc. Get more: Maths symbols Mean is the average value of the given set of observations.
