![**Margin of Error Calculation for Estimating a Population Mean**
**Problem Statement:**
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 20 with a mean of 55.2 and a standard deviation of 6.6 at a confidence level of 90%.
**Instructions:**
- Report \( M.E. \) accurate to one decimal place as the sample statistics are presented with this accuracy.
- Answers should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
**Input Box:**
\[ M.E. = \]
