**Using Sample Data and Confidence Levels for Estimation**
In a study examining the relationship between cell phone use and brain hemispheric dominance, an Internet survey was conducted. The survey was e-mailed to a randomly selected group of 2,660 subjects from an online community. Out of these, 1,088 surveys were returned. Your task is to construct a 90% confidence interval to estimate the proportion of surveys that were returned.

This exercise involves understanding how to use statistical methods to estimate population parameters from sample data. In this case, the focus is on calculating the proportion of returned surveys and constructing an appropriate confidence interval to make inferences about the broader population.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F860b79ae-d4fb-4102-b46c-c3e952761508%2Fbc1af618-552c-48ac-8bf6-8a0468bbfdcb%2Fj8ikgk_processed.jpeg&w=3840&q=75)
