To find the empirical probability, we divide the number of employees with a group health insurance plan by the total number of employees surveyed. 
Empirical Probability = Number of employees with group health insurance plan / Total number of employees surveyed 
Empirical Probability = 711 / 573 
Empirical Probability = 1.24 (rounded to the nearest hundredth) 
Therefore, the best choice is D, 0.81, as it is the closest value to 1.24 when rounded to the nearest hundredth.
