I have included two links. A normal random variable is a random variable whose associated probability distribution is the normal probability distribution. By definition, a random variable has to have an associated distribution. The normal distribution (probability density function) is defined by a mathematical formula with a mean and standard deviation as parameters. The normal distribution is ofter called a bell-shaped curve, because of its symmetrical shape. It is not the only symmetrical distribution. The two links should provide more information beyond this simple definition.

In Statistics define the 4 ARMC criteria?
1. variable is an antecedent 2. random assignment 3. values are maniipulated 4. controls
What is the probability that the random variable has a value less than 5?
That depends on the rules that define the random variable.

Is the normal probability distribution applied to a continuous random variable?
Yes.
Is the gender of college students a discrete random variable a continuous random variable or not a random variable?
It is a discrete random variable.

When it is random it is variable.
Define p-value vs - z score?
The p-value is the probability of any event or the level of significance for any statistical test. The z-score is a transformation applied to a Random Variable with any Normal distribution to the Standard Normal distribution.

Define continuous random evevt?
Usually we consider a random variable which assigns a value to the outcome of an event. The value assigned to the outcome can be either discrete or continuous. The continuous random variable is a random variable whose domain is defined over a continuous range. Examples: Daily inches of rain, speed of cars on highway, purchases made everyday at grocery stores.
How do you define a variable?
I define an variable by saying x- an value
Is the random variable x equals 1 be stated that the random variable is discrete?
If x = 1 then X is not really a random variable but a constant.

Suppose a normal random variable has a mean of 72 inches and a standard deviation of 2 inches. Suppose the random variable X measures the height of adult males in a certain city. One may therefore conclude that approximately 84% of the men in this population are shorter than?
