When can you say the distribution is considered normal?
When its probability distribution the standard normal distribution.
What are the characteristics a standard normal probability distribution?
I apologize my question should have read what are the characteristics of a standard normal probability distribution? Thank you
Why is the standard normal probability distribution unique?
a mean of 1 and any standard deviation
What requirements are necessary for a normal probability distibution to be a standard normal probability distribution?
The mean must be 0 and the variance must be 1.

.0401

What is Normal of probability distribution?
with mean and standard deviation . Once standardized, , the test statistic follows Standard Normal Probability Distribution.
Is normal distribution also a probability distribution?
Yes. When we refer to the normal distribution, we are referring to a probability distribution. When we specify the equation of a continuous distribution, such as the normal distribution, we refer to the equation as a probability density function.
What is Normal of Standard Normal Probability Distribution?
with mean of and standard deviation of 1.
Distinguish between binomial distribution and normal distribution?
Normal distribution is the continuous probability distribution defined by the probability density function. While the binomial distribution is discrete.
The mean of a standard normal probability distribution?
Zero.
What is The normal probability distribution with µ equals 0 and σ equals 1?
It is the Standard Normal distribution.
How does the standard normal distribution differ from the t-distribution?
The normal distribution and the t-distribution are both symmetric bell-shaped continuous probability distribution functions. The t-distribution has heavier tails: the probability of observations further from the mean is greater than for the normal distribution. There are other differences in terms of when it is appropriate to use them. Finally, the standard normal distribution is a special case of a normal distribution such that the mean is 0 and the standard deviation is 1.
Why is the standard normal probability distribution unique?
a mean of 1 and any standard deviation
What requirements are necessary for a normal probability distibution to be a standard normal probability distribution?
The mean must be 0 and the variance must be 1.
Define a normal random variable?
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.
