No. Normal distribution is a continuous probability.

Because very many variables tend to have the Gaussian distribution. Furthermore, even if the underlying distribution is non-Gaussian, the distribution of the means of repeated samples will be Gaussian. As a result, the Gaussian distributions are also referred to as Normal.

No, the normal distribution is strictly unimodal.

It is a continuous parametric distribution belonging to the family of exponential distributions. It is also symmetric.

with mean and standard deviation . Once standardized, , the test statistic follows Standard Normal Probability Distribution.

A bell shaped probability distribution curve is NOT necessarily a normal distribution.

The normal distribution, also known as the Gaussian distribution, has a familiar "bell curve" shape and approximates many different naturally occurring distributions over real numbers.
