Rohit wants to find the best model for a bivariate data set. He used a calculator to create a linear model, a quadratic model, a
nd an exponential model. The coefficient of determination for the linear model was 0.85. The coefficient of determination for the quadratic model was 0.90. The coefficient of determination for the exponential model was 0.81. Which model should he use to represent the data set?

Answer:
The number generator is fair. It picked the approximate percentage of red lollipops most of the time.
Step-by-step explanation:
The other answer choices represent various misinterpretations of the nature of the experiment or the meaning of the numbers generated.
___
A number generator can be quite fair, but give wildly varying percentages of red lollipops. Attached are the results of a series of nine (9) simulations of the type described in the problem statement. You can see that the symmetrical result shown in the problem statement is quite unusual. A number generator that gives results that are too ideal may not be sufficiently random.
