The correct answer option is: d
The relative frequency as a percentage of males and females who ride their bike to school compared to the total population, you need some additional information. Let's denote the following:
- Let M be the number of males who ride their bike to school.
- Let F be the number of females who ride their bike to school.
- Let T be the total population.
The relative frequency for males (RFM) is given by (M/T), and the relative frequency for females (RFF) is given by (F/T).
The total relative frequency for both males and females is (M + F)/T.
Now, you want to express this total relative frequency as a percent to the nearest tenths. The formula to convert a fraction to a percentage is to multiply by 100.
So, the percentage would be:
Percentage = (M + F)/T * 100
Without knowing the actual values of M, F, and T, we can't compute the exact percentage. However, we can estimate based on the provided options.
Therefore, the correct answer option is (d), the relative frequency is approximately 0.18 or 18%.
