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
Answer
Explanation:
Step1: Find the observed value
Locate $x = 5$ on the scatter - plot. The corresponding $y$ - value of the data point at $x = 5$ is 4.
Step2: Find the predicted value
Locate $x = 5$ on the line of best - fit. The corresponding $y$ - value on the line of best - fit at $x = 5$ is 5.
Step3: Calculate the residual
The formula for the residual is $e=y-\hat{y}$, where $y$ is the observed value and $\hat{y}$ is the predicted value. So, $e = 4 - 5=-1$.
Answer:
The observed value is 4. The predicted value is 5. The residual is - 1.
