1. The problem asks to determine if each situation results in data with variability (V) or no variability (NV). 2. Variability means the data values can change or differ; no variability means the data values are constant or fixed. 3. Analyze each statement: - 6. Number of minutes during first period class at Lamar Middle School: This is fixed for all students, so no variability (NV). - 7. Number of school holidays in 2018: This is a fixed number for the year, so no variability (NV). - 8. Number of people in a grocery store at 9 A.M. on a Saturday: This can change daily, so variability (V). - 9. Number of inches it rained over the past three weeks: Rainfall varies, so variability (V). - 10. Number of students absent from school for the past week: This number changes daily, so variability (V). - 11. Number of points scored in last Saturday's football game: This is a fixed number after the game, so no variability (NV). - 12. Number of students performing in the half-time shows: This is usually fixed for the event, so no variability (NV). Final answers: 6: NV 7: NV 8: V 9: V 10: V 11: NV 12: NV
