Question

use the scatterplot and line of best fit shown to complete the statements. when x = 5, the observed value is, the predicted value is, the residual is

Explanation:

Step1: Find the observed value

Locate $x = 5$ on the x - axis, then find the corresponding y - value of the data point. The observed value (the actual data point value) at $x = 5$ is 4.

Step2: Find the predicted value

Locate $x = 5$ on the x - axis, then find the corresponding y - value on the line of best fit. The line of best fit at $x = 5$ has a y - value of 7.

Step3: Calculate the residual

The residual is calculated as the observed value minus the predicted value. Residual=Observed - Predicted. So, residual = 4 - 7=- 3.

Answer:

The observed value is 4.
The predicted value is 7.
The residual is - 3.
