choose the regression model.
The Linear Regression (mx+b) dialog box opens.
2. Type a[] as the column for the X List.
3. Type b[] as the column for the Y List.
4. To store the regression equation in a specified variable, replace Save RegEqn To
with the name of the variable.
5. Type c[] as the column for the 1st Result.
