**Survey Insights on Online Bill Payments:**- **Survey Overview:** Out of a total of 2,755 adults surveyed, 1,447 individuals reported that they have started paying bills online within the last year.- **Objective:** The task is to construct a 99% confidence interval for the population proportion and to interpret the results accurately.- **Confidence Interval:** - The resulting 99% confidence interval for the population proportion is represented by open brackets [ ]. - Users are advised to round their final calculations to three decimal places as necessary for precision. Understanding confidence intervals is crucial in evaluating the reliability and significance of survey results within educational and practical applications.

Here, the number of adults have started paying bills online in the last year, x is 1,447and the…
