To find : The average enrollment in H.S.School.

           Average =\frac{\text { Sum of the terms }}{\text { Number of terms }}

Given :

Enrollment   No. of schools            

20 - 39                526                                          

40 - 59                620              

60 - 79                674

80 - 99                717

100 - 119             681

120 - 139             612

140 - 159            540

160 - 179             517

180 - 199             552

Total                5439

Finding the average enrollment :

Sum of the terms = 5439

Number of terms = 9

 Average =\frac{\text { Sum of the terms }}{\text { Number of terms }}

Average = \frac{5439}{9}

               = 604.33

Therefore, the average enrollment is 604.33.
