You add the two numbers and divide by two to get their average, of the number that would be midway (also a midpoint for visualization) between them. Find the least common denominator, which should be 9. Thus, you will multiply both the numerator and denominator of 7/3 by 3 to retain the ratio. You should get 21/9. Now, add 21/9 and 5/9 to get 26/9. That should be your answer, but make it a mixed number so you don't have an improper fraction.

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).
