Final answer:
The statement is true; Excel software provides the regression equation directly in the output of regression analysis, along with other key statistics like the correlation coefficient and the coefficient of determination.
Step-by-step explanation:
It is true that regression output from Excel software directly shows the regression equation. When using Excel for statistical analysis, you can perform linear regression using the software's built-in functions.
After inputting data and running a regression analysis, Excel provides comprehensive output which includes the regression equation of the form y = a + bx, where a represents the y-intercept and b represents the slope coefficient.
The output will also display the regression line on a graph if requested, providing a visual representation of the data and the relationship between the dependent and independent variables. Furthermore, the Excel output includes other significant statistics such as the correlation coefficient (r) and coefficient of determination (r²), which is the square of the correlation coefficient, typically presented as a percentage.
