Question

Hello,

I'm not sure why I am getting the first part of the question wrong 

A sample of 503 school teachers, who are married, showed that 210 of them hold a second job to supplement their incomes. Another sample of 383 school teachers, who are single, showed that 141 of them hold a second job to supplement their incomes. The null hypothesis is that the proportions of married and single school teachers who hold a second job to supplement their incomes are not different. The alternative hypothesis is that the proportions of married and single school teachers who hold a second job to supplement their incomes are different. The significance level is 5%. What is the 95% confidence interval for the difference between the proportions of married and single school teachers who hold a second job to supplement their income, rounded to four decimal places? to 0.1141
