A business statistics professor at a college would like to develop a regression model to predict the final exam scores for students based on their current? GPAs, the number of hours they studied for the? exam, and the number of times they were absent during the semester. The data for these variables are in the accompanying table. Complete parts a through d below.

F= ?(Round to one decimal place as? needed.)Calculate the? p-value. The? p-value is ?(Round to three decimal places as? needed.)State the conclusion. Choose the correct answer below. A. Since the? p-value is less than alpha?, reject the null hypothesis. The overall regression model is significant at the alpha= 0.05 significance level. B. Since the? p-value is greater than alpha?, do not reject the null hypothesis. The overall regression model is not significant at the alpha=0.05significance level. C. Since the? p-value is greater than alpha ?, do not reject the null hypothesis. The overall regression model is significant at the alpha=0.05 significance level. D. Since the? p-value is less than alpha?, reject the null hypothesis. The overall regression model is not significant at the alpha=0.05 significance level. d). Calculate the adjusted multiple coefficient of determination. R^{2}_{A}= (Round to three decimal places as? needed.)
