High school students in a sophomore class were asked whether they are left-handed or right-handed. A table showing the frequency of the handedness of the students is given.
Handedness
Frequency
Left-Handed
72
Right-Handed
478
To find the relative frequency of sophomores that are left-handed we divide its frequency by the number of sophomores. To find the number of sophomores, we add the frequencies.
72+ 478= 550
Now that we know the number of sophomores, we can find the relative frequency of sophomores that are left-handed.
72/550=36/275
