Suppose you are an educational researcher, and want to investigate the preferences of students for fully asynchronous classes. You survey 449 students, and find that 71 of them prefer asynchronous classes. Using this information, create a 95% confidence interval around the sample proportion. What is the lower bound (lower end) of the confidence interval? Round your final answer to three decimal places. Choose the value that is closest to your answer. 0.202 0.179 0.114 0.062 0.124
