According to a 2010 report from the American Council on ducation, females make up 531% of the college population in the United States. Students in a statistics class at South TexasCollege want to determine the proportion of female students at STC. they select a random sample of 135 STC students and nd that ?2 are female. which is a sample proportion of 72 t 135 a 0.533. So 53.3% of the students in the sample are female. What can they conclude about the proportion of females at the college? How confident can they be in their estimate? To answerthese questions. we need to nd a condence interval.{ estimate the population proportion within approximately 2 standard errors. 1 _ E = 2* p ( p) n and for the confidence interval use p': marginal of Error You Task: 1.Find Marginal of Error 2. Find condence interval 3. Conclusion: We are 9591: condent that the proportion of all STC students who are female is between -_ and
