Information was collected from employee records to determine whether there is an association between an employee's age and the number or workdays they miss. Excel results are summarized below: From this printout you determine:
A) the employee age is the dependent variable.
B) the employee age is the independent variable.
C) the regression equation is Y = 23.57 - 8.3x.
D) the regression equation is Y = 23.57 x - 0.45.
E) the employee age is the independent variable; the regression equation is Y = 23.57 + 0.45x.

In regression analysis, the dependent variable is predicted based on the values of the independent variable. In this case, workdays missed is the dependent variable and employee age is the independent variable. Therefore, answer B is correct. The regression equation provided in option E is incorrect, as the coefficient value for the independent variable should be negative based on the given data.
