The regression constant is the value of Y when X (the independent variable) is equal to 0. In this case, the independent variable is the number of economics courses the employee successfully completed in college. Looking at the data in the table, none of the workers completed 0 economics courses. Therefore, we cannot directly calculate the regression constant. However, we can use the regression equation to estimate it. Using the data given, we can find the regression equation: 
Y = 6.932 + 0.616*X 
where Y is the wage rate and X is the number of economics courses. 
Therefore, the regression constant is 6.932, which is choice C.
