Just as we did before, we will base both our confidence interval and our hypothesis test on the sampling distribution model.

Basic Elements of Bayesian Analysis
... Basic Elements of Bayesian Analysis In a frequentist analysis, one chooses a model (likelihood function) for the available data, and then either calculates a p-value (which tells you how unusual your data would be, assuming your null hypothesis is exactly true), or calculates a confidence interval. ...

Two-Sample Problems
... In order to make inferences about the differences between the two groups in the population, the sample size, mean, and standard deviation for each group must be known. These statistics are automatically computed by statistical software when estimating a confidence interval or conducting a test of si ...
