    Answer:

    A (52,2%, 55,8%)

    Step-by-step explanation:

    To get the confidence interval, we have to add the margin of error to the point estimator.

    The middle of the interval is 54%, and the ME is 1.8%. Don’t forget that this means ±1.8%!

    54 – 1.8 = 52.2%

    54 + 1.8 = 55.8%

    So our confidence interval is (52,2%, 55,8%) and the answer is A.
