Answer:
30.3%
Step-by-step explanation:
Add up the number of students in all age groups:
6 + 10 + 3 + 5 + 7 + 2 = 33
Look at the age group 19-22 and see that there are 10 students in that group.
To find the relative frequency, divide the number of students in the age group 19-22 (10) by the total number of students (33).
Calculate the relative frequency as a decimal:
10 / 33 = 0.3030
Convert the decimal to a percentage:
0.3030 × 100 = 30.3 %
