Perform hypothesis test

Complete the following steps to perform a hypothesis test and to specify a hypothesized value. For more information, go to What is a hypothesis test?
  1. Select Perform hypothesis test to determine whether the population median (denoted as η) differs significantly from the hypothesized median (denoted as η0) that you specify. If you don't perform the test, Minitab still displays a confidence interval, which is a range of values that is likely to include the population median.
  2. Enter a value in Hypothesized median. The Hypothesized median defines your null hypothesis (H0: η = η0). Think of this value as a target value or a reference value. For example, a chemist enters 12 as the test median to determine whether the median time that an antacid takes to relieve symptoms is different from 12 minutes (H0: η = 12).
