A randomly selected sample of 400 students is surveyed about whether additional coed dorms should be created at their school.
Of those surveyed, 57% say that there should be more coed dorms. The 95% margin of error for the survey is 5%. Compute a 95% confidence interval for the population percentage in favor of more coed dorms.
On the basis of this confidence interval, can we conclude that more than 50% of all students favor more coed dorms? Explain. Can we reject the possibility that the population proportion is .60?
