3. the table shows the results of a survey about the number of bus riders at mcguffey junior high. find the relative frequencies. round to the nearest hundredth. are male students or female students more likely to not ride the bus? explain. (example 3)
Answer
Explanation:
Step1: Calculate relative - frequencies for male students
The relative - frequency of male students who ride the bus is $\frac{110}{321}\approx0.343$. The relative - frequency of male students who do not ride the bus is $\frac{85}{321}\approx0.265$.
Step2: Calculate relative - frequencies for female students
The relative - frequency of female students who ride the bus is $\frac{84}{321}\approx0.262$. The relative - frequency of female students who do not ride the bus is $\frac{42}{321}\approx0.131$.
Step3: Compare relative - frequencies
For male students, the sum of relative - frequencies of riding and not riding the bus is $0.343 + 0.265=0.608$. For female students, the sum of relative - frequencies of riding and not riding the bus is $0.262+0.131 = 0.393$. Since $0.343>0.262$ and $0.265>0.131$, male students are more likely to ride or not ride the bus.
Answer:
Male students are more likely to ride or not ride the bus.
