Quizplus · Accepted Answer

The slope of the regression line is determined by the formula for the slope in linear regression, which involves the correlation between the two variables, the standard deviation of the dependent variable, and the standard deviation of the independent variable. The correct slope value, 0.6337, is calculated based on the given data and the application of this formula.
