The accompanying data are from a football league for one season. a. Construct a scatter diagram for points/game and yards/game. Does there appear to be a linear relationship? b. Use the Regression tool to develop a model for predicting points/game as a function of yards/game. Explain the statistical significance of the model and the Upper R squared value. Determine the coefficient of determination, Upper R squared, and interpret its meaning. Select the correct choice below and fill in the answer box to complete your choice. (Round to three decimal places as needed.) A. The coefficient of determination is Upper R squaredequals . 798. This value is the probability that the slope of the regression line is statistically significant. B. The coefficient of determination is Upper R squaredequals . 798. This value is the probability that the correlation between the variables is statistically significant. C. The coefficient of determination is Upper R squaredequals enter your response here. This value is the proportion of variation in points/game that is explained by the variation in yards/game. D. The coefficient of determination is Upper R squaredequals enter your response here. This value is the proportion of variation in yards/game that is explained by points/game
