The Student's T- Distribution is a type of probability distribution that is theoretical and resembles a normal distribution. The Student T- Distribution differs from the normal distribution by its degrees of freedom.
No they are not the same.
Check the lecture on t distributions at StatLect. It is explained there.
standard normal is for a lot of data, a t distribution is more appropriate for smaller samples, extrapolating to a larger set.
It approaches a normal distribution.

Given T=Z/√(U/ν), Z~N(0,1) and U~χ_ν^2, T follows the Student t-Distribution t_ν Student t-Distribution
Given T=Z/√(U/ν), Z~N(0,1) and U~χ_ν^2, T follows the Student t-Distribution t_ν Student t-Distribution
No they are not the same.
there is no pdf in hottling t sq test there is only mdf or it has multivariate distribution function

Z is the standard normal distribution. T is the standard normal distribution revised to reflect the results of sampling. This is the first step in targeted sales developed through distribution trends.
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.
Exponential distribution is a function of probability theory and statistics. This kind of distribution deals with continuous probability distributions and is part of the continuous analogue of the geometric distribution in math.
Each different t-distribution is defined by which of the following? @Answer found in section 4.3 The One-sample t-Test, in Statistics for Managers
Yes.
