$100. They estimate that such bills range from $600 to $2‚500. How large a sample should they take? The margin of error for this confidence interval for the mean is 100=Z*SD/sqrt(n). To solve for N: sqrt N=Z*SD/1.645‚ now square both sides: N=[Z*SD/100]^2 The Z score for a 90% confidence interval is 1.645.
