In a questionnaire, a random sample of students were asked whether they studied for more than four hours to prepare for an upcoming chapter test. The questionnaire resulted in a sample proportion of p' = 0.58, with a sampling standard deviation of ay = 0.11, who studied more than four hours. Write a 99.7% confidence interval for the true proportion of students who studied for more than four hours.
