Standard normal distribution: How to Find Probability (Steps) Step 1:Draw a bell curveand shade in the area that is asked for in the question. The example below shows z > -0.8. That means you are looking for the probability that z is greater than -0.8, so you need to draw a vertica...
in ahypothesis test, the absolute value is taken of a test statistic because it defines extremes (tail areas) at both ends of a probability distribution. When deciding toreject or support the null hypothesis, we care if a value falls into one of these tail areas — it doesn’t matter whi...
Obviously, this is avery long list.Either scroll down to find the type of function you want to learn more about, click a letter in the A-Z list below, or press Ctrl + F on your keyboard to search for specific types of functions. As an alternative, you can use the Google search box...
As a simple example, the two-dimensional coordinates {x, y} are perpendicular to each other. So two polynomials that each fit along the x and y axes are orthogonal to each other. When we talk about “orthogonal polynomials” though, we actually mean anorthogonal polynomial sequence. In other...
