Question

question #1
determine the relative frequency for the third class of the frequency distribution.
height (in.) frequency
60 - 64 1
65 - 69 3
70 - 74 13
75 - 79 8
80 - 84 5
13/17
5/17
3/30
13/30

Explanation:

Step1: Calculate total frequency

Total frequency \(n = 1+3 + 13+8+5=30\)

Step2: Find relative frequency formula

Relative frequency \(=\frac{\text{Frequency of the class}}{\text{Total frequency}}\)
For the third class (frequency \(= 13\)), relative frequency \(=\frac{13}{30}\)

Answer:

\(\frac{13}{30}\) (i.e., the fourth option \(13/30\))
