Two-step process will be used for selecting an SRS using random digit table.

1) Label each complex from 01 to 33 alphabetically. We have added labels 01 to 33 to the alphabetized list of complex below:

2) Using random digit table, Start at the left-hand side of line 117 and read two-digit groups. Select first 3 unique numbers ranging from 01-33, which will be selected complex, since our complexes are labeled 01-33. If number is repeated use only once, since same complex cannot be selected more than once.

Here is the beginning of the line 117:

  

Group the above digits to two-digit numbers. We get:
