![]() Once you have the proper test chosen, the process is very similar for each of the tests. You will need to go to Stats / Basic Statistics and choose the proper kind of test. Test Statistics, P-Values, and Confidence Intervals Once you find this critical value, the right critical value is its opposite. If it is a two tail test, then the area to the left of the left critical value is α / 2.If it is a right tail test, then the area to the left is 1 - α.If it is a left tail test, then the area to the left is the significance level α.Choose Input constant and enter the area to the left of the critical value for the constant.Enter the degrees of freedom if you have a Student's t distribution.Choose Calc / Probability Distributions / t if you are using the Student's t distribution.Choose Calc / Probability Distributions / Normal if you are using the standard normal distribution. ![]() Minitab requires the area to the left of the critical value. That is, a left tail test should have a negative critical value, a right tail test should have a positive critical value, and a two tail test should have both a positive and negative critical value. There should always be as many critical values as tails and the signs should agree.
