Regression. A coach wants to see the relationship between the statistics of practice games and official games of a local soccer team. A sample of 14 players was used and the resulting (partial) Excel output is shown below. Assume both x and y form normal distributions. Regression Multiple R R Square Adjusted R Square Standard Error Observations Statistics *** 0.70524 0.668395 8.703633 14 Coefficients Standard (a) The slope of the regression line is A. 4.378 OB. 40.66 OC. 0.717 OD. 0.175 t Stat P-value Lower CHE Upper
