Answers:
1.
Male Female Total
Walking 9 8 17
Ride the Bus 16 26 42
Carpooling 19 24 43
Total 44 58 102
2. 3/34
3. 24/43
4. Carpooling
Explanation:
Taking into account the information of the question we get that:
There are 44 male students and they are distributed as:
Walk: 9
Ride the bus: 16
Carpooling: 44 - (9 + 16) = 19
In the same way, there are 58 female students distributed as:
Walk: 58 - (26 + 24) = 8
Ride the bus: 26
Carpooling: 24
Therefore, we can make a two-way table as:
Male Female Total
Walking 9 8 17
Ride the Bus 16 26 42
Carpooling 19 24 43
Total 44 58 102
Now, the proportion of students who are female and walk to school is:
[tex]\text{Proportion = }\frac{9}{102}=\frac{9\div3}{102\div3}=\frac{3}{34}[/tex]Because there are 102 students and 9 of them are female and walk to school.
In the same way, of the students who carpool, the proportion of females is:
[tex]\text{Proportion}=\frac{24}{43}[/tex]Finally, I would predict that the mode of transportation is Carpooling because 43 is greater than 17 (students that walk) and 43 is also greater than 42 ( students that ride a bus).
So, the answers are:
1.
Male Female Total
Walking 9 8 17
Ride the Bus 16 26 42
Carpooling 19 24 43
Total 44 58 102
2. 3/34
3. 24/43
4. Carpooling
