Looking at this box and whisker plot, I need to identify the values for each component.
Let me work through this step by step:
1.
Lower Extreme (minimum value): Looking at where the leftmost point aligns with the number line below, it's at 60.
2.
Lower Quartile (Q1): The left edge of the box aligns with 70 on the number line.
3.
Median (Q2): The line inside the box aligns with 80 on the number line.
4.
Upper Quartile (Q3): The right edge of the box aligns with 90 on the number line.
5.
Upper Extreme (maximum value): The rightmost point aligns with 100 on the number line.
Let me verify these readings:
- Lower Extreme: Point is directly above 60 ✓
- Lower Quartile: Box starts at 70 ✓
- Median: Line in middle of box is at 80 ✓
- Upper Quartile: Box ends at 90 ✓
- Upper Extreme: Right point is at 100 ✓
The five-number summary for this box and whisker plot is:
- Minimum: 60
- Q1: 70
- Median: 80
- Q3: 90
- Maximum: 100
Final Answer:
Lower Extreme = 60, Lower Quartile = 70, Median = 80, Upper Quartile = 90, Upper Extreme = 100
