I plugged in 51.7 for x in the linear regression equation and got 49.6 cm for the answer, but it is supposed to be 40.8. Is there a different method of doing this?

Answer :

Final answer:

The error in the student's result from the linear regression equation could be due to incorrect calculations or false input values. It's important to ensure the right coefficients are used and that the equation's instructions are thoroughly followed.

Explanation:

The discrepancy in your result may be due to a mistake in the calculation process, which involves inputting the value of x into your linear regression equation. To ensure accuracy, the equation, which is often expressed in the form y = mx + c (where m is the slope and c is the y-intercept), must be followed strictly. Ensure your x value is multiplied by the slope and then add the y-intercept. Make sure your coefficients (m and c) values are correct; a slight error in these values can affect your result. Lastly, ensure no arithmetic errors were made during calculations.
