We have conducted an option 3, approach 2 (sample survey) for our project. The reference guide notes that if an occupant reports being absent due to vacation or a sick day, that it should accounted for but not included in the results. If we understood this correctly, does this result in a reduced the baseline (sample size) by the appropriate number of vacation/sick days and not assign a number in our survey results?

For example: a sample size of 300 surveys is needed. Out of the 300 surveys conducted, 10 respondents reported vacation/sick days. The sample size is now reduced for 290. Now we compare the survey results with the new sample size? Is this correct? Note: occupants are assumed to go to and from the building in the same manner.
