The image is a photograph of a MacBook Air displaying a webpage related to statistical analysis. The webpage presents a problem statement regarding the commute times in a community, asking to find and interpret a 95% confidence interval. **Text on the Webpage:** "A sample of 30 commuters in this area of a certain city yielded the accompanying commute times in minutes. Develop a 95% confidence interval with these data by following the procedure outlined in the Procedure section. (Round to one decimal place as needed.)" There is also a data input box titled "Commute times" which lists the following times: 22, 28, 39 26, 42, 29 11, 27, 37 21, 39, 15 34, 21, 29 32, 30, 28 58, 16, 32 38, 45, 38 46, 20, 17 16, 40, 37 Below the data input box are options for "Print" and "Done." **Context:** The task is likely part of an educational exercise to calculate a confidence interval for the provided commute times, useful in learning statistical methods and data analysis. **Additional Interface Elements:** The left side of the screen displays multiple app icons, including Safari, Apple Music, Photos, and others on the MacBook's dock. The keyboard appears to have a pink cover.
