To evaluate the correct interpretation of the data based on the relative frequency table provided, let's break down the given percentages:
- Third Graders (with a pet): 16%
- Third Graders (without a pet): 19%
- Fourth Graders (with a pet): 29%
- Fourth Graders (without a pet): 36%
- Totals:
- With a pet: 45%
- Without a pet: 55%
Now, we can analyze the potential interpretations:
-
The smallest joint relative frequency is third graders without a pet.
- Third graders without a pet: 19%
- This is not the smallest; the smallest is the third graders with a pet (16%).
-
Most students in the sample have a pet.
- Total with a pet: 45%
- This is not a majority, as most means over 50%.
-
More fourth graders responded than third graders.
- Fourth graders: 65% (total) vs. Third graders: 35% (total)
- This statement is correct since more fourth graders responded.
-
The largest joint relative frequency is fourth graders with a pet.
- Fourth graders with a pet: 29%
- The largest joint relative frequency is actually fourth graders without a pet (36%).
Based on the analysis, the correct interpretation of the data is:
More fourth graders responded than third graders.
