Hi, thank you for posting your question here at Brainly.
First, we find the center of the range through ratio and proportion:
111/210 = x/903
x = 477
Since there is a 4% margin error,
477(0.04) = 19, we subtract and add 19 to 477 to determine the lower and the upper limit of the range, respectively.
477  19 = 458
477 + 19=496
Therefore, the range is 458 to 496.
