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

Open intervals are expressed in interval notation using parentheses. For example, the interval (4, 9) means 4 < x < 9, with the 4 and the 9 excluded. Why is it called a closed interval? A closed interval is an interval in which the endpoints are included. It is closed because there...
where the notation is used to indicate that the probability is calculated using the distribution function associated to the true parameter . In this definition, the random quantity is the interval , while the parameter is fixed. How the coverage probability is chosen ...
We can also represent this set by using a number line; we want to include all of the values between 0 and 2 but not the endpoints. We do this by using open circles to show that 0 and 2 are not included, as shown. Before we formally define interval notation, we should note that so...
