A global corporation is currently in the process of expanding its operations, and the only option is to move to another site. The Human Resource Team has conducted a survey to its employees who live far from the site in order to find out if they are willing to stay in dormitories. The survey categorizes its respondents according to gender. In the samples sample of 500 males and 800 females, those who are willing to stay in dormitories are 241 and 168, respectively. Construct a 98% confidence interval for the difference between the two population proportions. Assuming that the HR’s estimated difference between the proportion of genders who are willing to stay in dormitories is 35%, is the team’s estimation accurate?
