Answer 1

To find the percentage of 8th-grade students who come to school by car, we need to divide the number of 8th-grade car riders (44) by the total number of 8th-grade students (100) and then multiply by 100.

(44 / 100) * 100 = 44%

So, 44% of 8th-grade students come to school by car.

To find the percentage of 7th-grade students who walk to school, we need to divide the number of 7th-grade walkers (16) by the total number of 7th-grade students (100) and then multiply by 100.

(16 / 100) * 100 = 16%

So, 16% of 7th-grade students walk to school.

To find the percentage of car riders who are 8th-grade students, we need to divide the number of 8th-grade car riders (44) by the total number of car riders (96) and then multiply by 100.

(44 / 96) * 100 = 45.8%

So, approximately 45.8% of the students who came to school by car are 8th-grade students.

To find the percentage of bus riders who are 7th-grade students, we need to divide the number of 7th-grade bus riders (32) by the total number of bus riders (70) and then multiply by 100.

(32 / 70) * 100 = 45.7%

So, approximately 45.7% of the students who rode the bus are 7th-grade students.

An example of a statistical investigative question that could be answered using this data is:

"Is there a relationship between grade level and mode of transportation to school?"

By analyzing the data, we can see that the percentage of 7th-grade students who walk to school is higher than the percentage of 8th-grade students who walk. Additionally, the percentage of 8th-grade students who come to school by car is higher than the percentage of 7th-grade students who come by car. This suggests a potential relationship between grade level and mode of transportation.
