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
