To determine the total number of employees Luz observed, we can add up the counts for each category:
-
Coffee:
- Before 9 am: 33
- After 9 am: 17
- Total for Coffee = 33 + 17 = 50
-
Tea:
- Before 9 am: 21
- After 9 am: 15
- Total for Tea = 21 + 15 = 36
-
Neither:
- Before 9 am: 11
- After 9 am: 14
- Total for Neither = 11 + 14 = 25
Now, adding all these totals together gives us:
Total Employees = 50 + 36 + 25 = 111
Next, to find which beverage preference had the highest percentage of people starting work after 9 am, we can calculate the percentages for each group that started after 9 am:
-
Coffee:
- Employees starting after 9 am: 17
- Total coffee drinkers: 50
- Percentage = (17 / 50) * 100 = 34%
-
Tea:
- Employees starting after 9 am: 15
- Total tea drinkers: 36
- Percentage = (15 / 36) * 100 ≈ 41.67%
-
Neither:
- Employees starting after 9 am: 14
- Total who drank neither: 25
- Percentage = (14 / 25) * 100 = 56%
From the calculations, we see that the beverage preference “Neither” had the highest percentage of employees starting after 9 am at 56%.
Putting it all together, Luz observed a total of 111 employees, and the beverage preference with the highest percentage of people starting work after 9 am was those who drank neither coffee nor tea.
The correct response is: 111; employees who drank neither coffee nor tea were mostly likely to start after 9 am.
