Answer: Hi, the answer is the margin of error would be 19 for 2 s.d. or 18.6 for 1.96 s.d
Step-by-step explanation: The margin of error needs to be defined, but if one uses 1.96 (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).
