The US Census Bureau provides a document to assist people with statistical inference using the data from the American Community Survey. Below is an excerpt from this document. Use the information given to fill in the value that goes in the two blanks.

All ACS estimates from tables on AFF include either the ? percent margin of error or ? percent confidence bounds. The margin of error is the maximum difference between the estimate and the upper and lower confidence bounds. Most tables on AFF containing 2005 or later ACS data display the margin of error. Use the margin of error to calculate the standard error (dropping the +/− from the displayed value first) as: Standard Error = Margin of Error/Z where Z = 1.645 for 2006 ACS data and recent years.

The American Community Survey, administered by the US Census Bureau, is given every year to a random sample of about 3.5 million households (about 3% of all US households). It has been crucial for government and policy decisions, and helps to determine how over 400 billion dollars of government funds are distributed each year. Unfortunately, the House voted in May 2012 to eliminate this valuable source of information. Data on a random sample of 1% of all US residents are made public (after ensuring anonymity), and we have selected a random sub-sample of n = 1000 from the 2010 data, stored in ACS.
