Question

Evalute the concept of normal and standard normal distribution

Answer 1

Normal distributions are denser in the center and less dense in the tails. Normal distributions aredefined by two parameters, the mean (μ) and the standarddeviation (σ). 68% of the area of anormal distribution is within onestandard deviation of the mean.

Answer 2

Both are normal distributions but standard normal distribution is a particular case of Normal distribution when the mean is 0 and standard deviation or variance is 1. This makes Y a “Standard” distribution. So basically X is Normally distributed and Y is “Standard” normally distributed
