WebStudent's t-test Up: Statistical inference Previous: Some definitions Confidence intervals for rejection. A confidence interval (CI) consists of the possible values that cannot be rejected of a hypothesis test whose H 0 is that ``the value of the observed sample statistic corresponds exactly to the population value it estimates''. The CI may be regarded as the … WebOct 7, 2024 · In such a scenario, the evidence the test provides is insufficient and, as such, cannot justify the rejection of the null hypothesis when it is actually false. The level of significance, denoted by α, represents the probability of making a type I error, i.e., rejecting the null hypothesis when it is actually true.

For the critical value approach we need to find the critical value (CV) of the significance level ($\alpha$).. For a population mean test, the critical value (CV) is a T-value from a student's t-distribution.. This critical T-value (CV) defines the rejection region for the test..
