Answer to Problem 144CR
The given scatter plotcould be best modeled by a quadratic model.
Explanation of Solution
Given information:
The scatter plot is shown in Figure- 1 here.
Methodused:
If the scatter plot represents the graph of line then the scatter plot could be best modeled by linear model, if it represent the graph of quadratic function (parabola) then it could be best modeled by quadratic model or if the scatter plot neither represents a line nor a parabola it could be best modeled by neither.
From figure -2 it is clear that the best fit curve ( a curve passing through maximum number of points) for scatter plot is a parabola, a quadratic function of the form
Hence, the given scatter plotcould be best modeled by a quadratic model.
Conclusion:
The given scatter plotcould be best modeled by a quadratic model.
