  • 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.
