A simple random sample of 40 students is taken at a community college. Of those, 25 are females. Use the proportion of females in the sample to construct a 95% confidence interval for the proportion of females enrolled on the campus (the population). Round your boundaries to two decimal places (for example(0.25, 0.35)).
