    Express the confidence interval 0.039 < p < 0.479 in the form of p ± E.

    We find the range of this interval:
    Range = Upper Bound - Lower Bound
    Range = 0.479 - 0.039
    Range = 0.44

    Each piece on opposite sides of p gets:
    0.44/2 = 0.22

    So our expression becomes
    p ± 0.22
