Interval notation is a method to represent an interval on a number line. In other words, it is a way of writing subsets of the real number line. An interval comprises the numbers lying between two specific given numbers. Understand interval notation bett

For a set {x | a < x < b} the open interval is denoted by the interval notation (a,b) where the real numbers a and b are not the part of the interval set. This can be represented on the number line as: The hollow circles on a and b denote that the real numbers denoted by...

Suppose, for example, X is normally distributed with a mean of 5 and a standard deviation of 10, for which we use the shorthand notation X ~ N[5, 10]. If we want to determine the probability that the value of X is larger than 15, the corresponding Z value is Z=X−μσ=15−...
