A university financial aid office polled a random sample of 528 male undergraduate students and 419 female undergraduate students. Each of the students was asked whether or not they were employed during the previous summer. 404 of the male students and 248 of the female students said that they had worked during the previous summer. Give a 80% confidence interval for the difference between the proportions of male and female students who were employed during the summer.

Step 1 of 3 : Find the point estimate that should be used in constructing the confidence interval. Round your answer to three decimal places.

Step 2 find the variance

step 3 find the standard deviation
