Sick Days 7E876E
1. **Stating the problem:** We are given a box and whisker diagram representing the number of sick days taken by employees in a year. We need to identify the minimum, lower quartile, and median from the diagram and analyze a claim about the distribution of sick days.
2. **Understanding the box and whisker diagram:**
- The minimum is the smallest value (left whisker end).
- The lower quartile (Q1) is the left edge of the box.
- The median (Q2) is the line inside the box.
- The upper quartile (Q3) is the right edge of the box.
- The maximum is the right whisker end.
3. **From the diagram:**
- Minimum number of sick days = 2 (left whisker end).
- Lower quartile (Q1) = 6 (left edge of the box).
- Median (Q2) = 11 (line inside the box).
4. **Answering part (a):**
(a.i) Minimum number of sick days = $2$
(a.ii) Lower quartile = $6$
(a.iii) Median = $11$
5. **Analyzing part (b):**
Paul claims: "The percentage of employees who took fewer than 6 sick days is smaller than the percentage who took more than 11 sick days."
- The lower quartile $Q1=6$ means 25% of employees took fewer than 6 sick days.
- The median $Q2=11$ means 50% took fewer than 11 sick days, so 50% took more than 11 sick days.
Therefore:
- Percentage with fewer than 6 sick days = 25%
- Percentage with more than 11 sick days = 50%
Paul's claim is correct because 25% < 50%.
**Final answers:**
- (a.i) Minimum = $2$
- (a.ii) Lower quartile = $6$
- (a.iii) Median = $11$
- (b) Paul is correct; fewer than 6 sick days corresponds to 25% of employees, which is less than the 50% who took more than 11 sick days.
