Re: Statistical Review: The Supporting Statement for OMB

I have read the supporting document for OMB and in particular reviewed the part on Statistical Methods. The proposed sampling design and procedures for collecting data, including information on non-respondents, is adequate and appropriate for this project.

If you have questions about this review, please feel free to contact me.
