We did find a nice spreadsheet from the Census Bureau that tells us the margin of error for different variables for that dataset, so we have something to “check” against. z P>|z| [95% Conf.

As Kelly and Maxwell (2003) state, "The AIPE approach yields precise estimates of population parameters by providing necessary sample sizes in order for the likely widths of confidence intervals to be Loading... The total number of predictors in the model is 5 and we want a confidence interval half-width of 0.1 with an alpha level of 0.05.
