A thought experiment about sampling distributions: Imagine you take a random sample of individuals from a target population, measure something and then calculate a sample statistic, the “mean” let’s ...

Give the form of a rejection region. Perform tests concerning a true population variance. Compute the sampling distributions for the sample mean and sample minimum of the exponential distribution. In ...
