During the recovery from the Great Recession of 2007-2009, the economic situation for many families improved.However, in 2011 the recovery was slow and it was uncertain as to how much had really changed on the national level.To estimate the national average of the percent of low-income working families, a representative simple random sample of the percent of low-income working families from each of the country's reporting jurisdictions could be used to calculate a point estimate and find a related confidence interval.With this confidence interval a better picture of the nation's recovery can be had and legislative decisions can be made.

1.Provide an explanation as to why it would be very unlikely that a different sample of size n=30 would produce the same confidence interval.
