For every additional year in the employee's age, the average number of absent days in the last year significantly (p-value<0.05) increases by
0.27 days.
For every additional year in employee's length of employment, the average number of absent days in the last year significantly (p-value<0.05)
decreases by 0.51 days.
None of the above is correct.
