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
