The t-distribution
Step-by-step explanation
first, the confidence interval is determined when the variable is continuous
second, the Binomial and hypergeometric distribution is used on discrete variables
third, if the deviation is not known and the sample is small, the distribution t
fourth the normal distribution is used when the deviation is known
