Enter data only in the blue cells. If entering raw data, delete any existing data before pasting your data in. You can enter your data with or without column labels.

If the problem does not state an assumed value for µ_d, enter 0. Use the orange cell drop-down menu to select the math operator of the claim. To get the math operator drop-down menu, left-click in the orange cell, e.g. on the current operator.
If you have raw data, click on the Paired-Raw Data tab and scroll right to find the blue columns. Or, you can click on the “rectangle” at the right end of the black bar at the very bottom to open the workbook in a larger window.
