Question 1121731
The margin of error needs to be defined, but if one uses 1.96 sd (95% by empiric rule for normal distributions), it is 3.72.  For 2 s.d, it is 3.61

The margin of error would be 19 for 2 s.d. or 18.6 for 1.96 s.d  The margin of error is +/-19, for example, the interval within the margin of error would be (186, 224).
