What are the characteristics of a standard normal distribution? Can two distributions with the same meanand different standard distributions be considered normal? How might you determine if a distribution is normal from its graphical representation?
A standard normal distribution is a normal distribution (symmetrical, bell-shaped, approaches zero at the extremes) with a mean of 0 and a standard deviation of 1.
I think for the second question you mean different standard deviation. If this is the case, …
This solution provides a detailed description of the characteristics of a standard normal distribution. It will be helpful for students looking to develop a deeper understanding of basic statistics.
