In 2019, а reseаrch study wаs cоnducted оn the sleeping habits оf George Mason students. The researchers were interested in trends of students who get at least 7 hours of sleep in a day. A random sample of George Mason students aged 18 to 24 was asked whether they slept at least 7 hours on an average night. The study was repeated in 2024. The number of George Mason students who reported getting at least 7 hours of sleep each night is shown in the table below. Slept at least 7hours 2019 2024 Total Yes 2,500 2,100 4,600 No 1,500 1,900 3,400 Total 4,000 4,000 Given the results of a bootstrap distribution above, construct the 95% confidence interval for estimating the parameter using the 2SE method.
