Z symbol in maths

A z test can further be classified into left-tailed, right-tailed, and two-tailed hypothesis tests depending upon the parameters of the data. In this article, we will learn more about the z test, its formula, the z test statistic, and how to perform the test for different types of data using examples.

In mathematics, the letter Z is often used to represent the set of integers, which includes all positive and negative whole numbers, as well as zero. It comes from the German word "Zahl", meaning number. stands for integers, including all negative and positive integers. Here are some of the rules for integers:The fish symbol (∝) is used to indicate that y is proportional to x. The fish symbol is often used in geometry, algebra, and other areas of math to represent proportionality.
