Looking for differences in the population means between two samples with a 2-Sample t-test

For this recipe, we will use a 2-Sample t-test to compare two groups of data. The null hypothesis for the 2-Sample t-test is that the population means are the same.

Here, we will look at comparing the pulse rate of a group of students that exercised against a group that didn't.

Getting ready

The data is in the Minitab Pulse.mtw worksheet. The file can be found in the Minitab Sample Data folder.

How to do it…

The following steps will compare the mean pulse rate of two groups of students:

1. To open the worksheet, go to the Stat menu and select Open Worksheet….
2. Click on the Look in Minitab Sample Data folder button.
3. Open the Pulse.mtw worksheet.
4. Go to the Stat menu and ...
