Answer:
63%
Explanation:
The coefficient of determination, R^2, represents the proportion of the variance in the dependent variable that can be explained by the independent variable(s). To convert the coefficient of determination from a decimal to a percentage, you multiply it by 100.
In this case, the coefficient of determination is given as 0.63. To find the percentage of R^2, we multiply 0.63 by 100:
0.63 * 100 = 63
Therefore, the percent of R^2 is 63%. Thus, the correct answer is option a. 63%.
