To create the conditional frequency table for students who prefer soda or water given they prefer hamburgers or hot dogs, we need to find the percentages of soda and water preferences among those who prefer hamburgers and hot dogs.
- Calculate the percentages for each drink based on hamburgers and hot dogs.
For Hamburgers:
-
Soda:
- Number of students who prefer hamburgers and soda = 41
- Total number of students who prefer hamburgers = 72
- Percentage = (41 / 72) * 100 = 56.94% ≈ 57%
-
Water:
- Number of students who prefer hamburgers and water = 31
- Total number of students who prefer hamburgers = 72
- Percentage = (31 / 72) * 100 = 43.06% ≈ 43%
For Hot Dogs:
-
Soda:
- Number of students who prefer hot dogs and soda = 20
- Total number of students who prefer hot dogs = 48
- Percentage = (20 / 48) * 100 = 41.67% ≈ 42%
-
Water:
- Number of students who prefer hot dogs and water = 28
- Total number of students who prefer hot dogs = 48
- Percentage = (28 / 48) * 100 = 58.33% ≈ 58%
- Construct the conditional frequency table:
Hamburgers (%) Hot Dogs (%) Total (%)
Soda 57 42 100
Water 43 58 100
So the final conditional frequency table looks like this:
Hamburgers (%) Hot Dogs (%) Total (%)
Soda 57 42 100
Water 43 58 100
You can now fill in the percentages on your table accordingly.
