Assume that a sample is used to estimate a population mean \( \mu \). Find the margin of error M.E. that corresponds to a sample of size 10 with a mean of 81.7 and a standard deviation of 9.1 at a confidence level of \( 99.9 \% \). Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. \[ \text { M.E. }= \] \( \square \) Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Step 1
- Sample size (n) = 10 - Sample mean (\(\bar{x}\)) = 81.7 - Sample standard deviation (s) = 9.1 - Confidence level = 99.9% Show more…
