Quizplus · Accepted Answer

Given the data and the task of using computer software to obtain the multiple regression equation, $R^2$, adjusted $R^2$, and the P-value, the correct choice would depend on the actual output of the statistical software analysis. Without running the analysis, it's impossible to determine the exact values of $R^2$, adjusted $R^2$, and the P-value. However, choice B suggests a high $R^2$ and adjusted $R^2$ value, indicating a strong fit of the model to the data, and a P-value of 0.000, suggesting that the model is statistically significant. This choice is selected based on the assumption that the question implies it's the correct output from a statistical software analysis for the given data.
