Quizplus · Accepted Answer

The coefficient of determination is a value between 0 and 1, and represents the proportion of the variation in the dependent variable that is explained by the independent variable. In this case, we do not have any information about the variables, but assuming they are related, the coefficient of determination must be between 0 and 1. Therefore, D is not a valid answer. To calculate the coefficient of determination, we need to perform a regression analysis, which is not possible with this information. Therefore, we must guess the answer. The closest answer to 1 (100%) is A, which is 91.8%, indicating that the independent variable explains 91.8% of the variation in the dependent variable. Therefore, A is the best choice.
