184.108.40.206 - Minitab Express: One Sample Mean t Tests
A hypothesis test for one group mean can be conducted in Minitab Express using raw data or summarized data.
- If you have a data file with every individual's observation, then you have raw data.
- If you do not have each individual's observation, but rather have the sample mean, sample standard deviation, and sample size, then you have summarized data.
The next two pages will show you how to use Minitab Express to conduct a one sample mean t test using either raw data or summarized data. There is also one example of using Minitab Express to conduct a one sample mean z test which is only performed if the population is known to be normally distributed and the population standard deviation (\(\sigma\)) is available.
