I'm trying to get an answer to this question, and a better explanation.

Males vs Females and One True Love In Data 2.1 on page 54, we describe a study in which a random sample of 2625 US adults were asked whether they agree or disagree that there is "only one true love for each person." The response and sex of the participants is shown in Table 3.6. Use the information in the table to construct and interpret a 95% confidence interval for the difference in the proportion who agree, between males and females, using the fact that the standard error for the difference is 0.018. Is it plausible that there is no difference between males and females in the proportion who agree that each person has only one true love?
