Question

given the data below are the number of students in each age group.
ages | number of students
15 - 18 | 3
19 - 22 | 8
23 - 26 | 9
27 - 30 | 3
31 - 34 | 5
35 - 38 | 4
based on the frequency distribution above, find the relative frequency for the class with lower class limit 35. give your answer as a percent, rounded to one decimal place.
relative frequency = %

Explanation:

Step1: Calculate total number of students

$3 + 8 + 9 + 3 + 5 + 4 = 32$

Step2: Identify target class frequency

The class with lower limit 35 (35-38) has 4 students.

Step3: Compute relative frequency (decimal)

$\frac{4}{32} = 0.125$

Step4: Convert to percent, round to 1 decimal

$0.125 \times 100 = 12.5$

Answer:

12.5
