To find the equation for the Linear Regression Line and the correlation between the test marks and the homework marks using the Desmos Graphing Calculator, please follow these steps:
1. Click on the provided link to access the Desmos Graphing Calculator.
2. Once the calculator is loaded, click on the table icon located at the top right corner of the calculator to open a table.
3. Input the data for the test marks and homework marks into the table.
4. After inputting the data, click on the graph icon (fourth icon from the left) to plot the points on a scatter plot.
5. Once the scatter plot is displayed, click on the wrench icon (first icon from the left) to open the settings menu.
6. In the settings menu, select "Add Item" and choose "Best Fit Line" from the dropdown menu.
7. The calculator will show the equation for the Linear Regression Line on the graph. Copy this equation as the response for part A.
Now, let's answer the questions using the responses:
A. The equation for the Linear Regression Line is: [Response area]
B. There is a [Response area] correlation between the test marks and the homework marks.
C. The slope of the line of best fit can be used to make a probabilistic interpretation that states [Response area].
