Answer:
The answer to your question is below
Explanation:
Chart
Number of Observed Predicted Residual
experience
5.1 12.2 12.45 0.25
7.1 14.2 14.25 0.05
The observed value was obtained from the graph
The predicted value was obtained using the equation
y = 0.9(5.1) + 7.86 = 12.45
y = 0.9(7.1) + 7.86 = 14.25
The residual was obtained from the subtraction of the observed and the predicted.
