Unformatted text preview: Critical region Set of all values which would cause us to reject H Critical value(s) The value(s) which separate the critical region from the noncritical region. The critical values are determined independently of the sample statistics. Significance level ( alpha ) The probability of rejecting the null hypothesis when it is true. alpha = 0.05 and alpha = 0.01 are common. If no level of significance is given, use alpha = 0.05. The level of significance is the complement of the level of confidence in estimation. Decision A statement based upon the null hypothesis. It is either "reject the null hypothesis" or "fail to reject the null hypothesis". We will never accept the null hypothesis.
