The coefficient for studying was not given, but since the coefficient for gaming is positive and significant, this means that as the time spent on gaming increases, the test score decreases. However, since the coefficient for studying was not negative or significant, it is safe to assume that studying has a positive and significant relationship with test score. Therefore, at the mean value of online gaming, there is a significant positive relationship between studying and test score.
