Title:
 On the type I and II errors in the sequential testing of hypothesis about a mean in normal population

Language: English

Keywords:
testing hypothesis
sequential test
type I and II errors
simulation

Summary:
In the sequential testing of hypotheses both the type I and II errors are under control. In this paper we focus on testing the hypothesis concerning mean value in normal population versus the simple alternative formulated in terms of standard deviation. The aim of this paper is to compare nominal errors type I and II with the empirical ones evaluated by means of simulation study.
