1. The problem asks to determine whether each question in the given situations is a statistical question. 2. A statistical question is defined as any question whose answer could involve working with more than one data value. 3. Let's analyze each situation: (a) Lena asked one neighbor, "What was the number of hours that you worked last week?" This involves only one data value from one person, so it is **not** a statistical question. (b) Carlos asked the people at his work, "How many jobs have you had in your life?" Since he asked multiple people, the answer involves multiple data values, so it **is** a statistical question. (c) Tammy asked several people in her town, "How much money did you spend on clothing last year?" Multiple people means multiple data values, so it **is** a statistical question. (d) Eric asked his coworker, "How many times did you shop online last month?" Only one person, so it is **not** a statistical question. (e) Hans asked twenty women at a local store, "How many cars does your family own?" Multiple people means multiple data values, so it **is** a statistical question. Final answers: (a) No (b) Yes (c) Yes (d) No (e) Yes
