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 - 0.45x.
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.

The Excel results suggest that employee age is the independent variable as it is being used to predict the number of workdays missed (the dependent variable). The regression equation provided in the summary shows that the predicted number of workdays missed (Y) is a function of employee age (x), with a slope of -0.45 and a y-intercept of 23.57. The correct format for this regression equation is Y = 23.57 - 0.45x.
