    Answer:

    The upper bound of the interval is below 0.5, which means that it can be claimed that a majority of people are not in favor of legalized abortion

    Step-by-step explanation:

    Confidence interval:

    Sample proportion plus/minus margin of error.

    In this question:

    Sample proportion of 0.45, margin of error of 0.04. So

    0.45 – 0.04 = 0.41

    0.45 + 0.04 = 0.49

    The confidence interval is of (0.41,0.49). The upper bound of the interval is below 0.5, which means that it can be claimed that a majority of people are not in favor of legalized abortion
