CI will be narrower, reflecting the greater precision of the individual measurements.
However, if the evidence is not strong enough, researchers fail to reject the null hypothesis.
Sampling saves money, time, and effort.
Its mean is a weighted average of the sample mean and the prior mean, weighted by the sample precision and prior precision, respectively.
This turns out to also be the maximum likelihood estimator.

See that in large samples, many sampling distributions can be approximated with a normal distribution. If there is a close agreement between the two cumulative distributions, the hypothesis that the sample was drawn from population with a normal distribution function is supported.
