You want to estimate the percentage of students at OSU who earn their undergraduate degrees in four years. You survey a random sample of 430 recent graduates and find that 57% of these graduates were able to complete the requirements for their degrees in four years. Use this information to construct a 90% confidence interval in order to estimate the proportion of all OSU undergraduates who earn their degrees in four years. As you construct the interval, round your sample proportion and margin of error to three decimal places as you are engaging in calculations, and choose the answer that is closest to what you calculate.
