Answer #1

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.

In z-distribution, population standard deviation is known whereas in t-distribution, population standard deviation is not known and sample standard deviation is known.
