Question

question #9
determine the relative frequency for the third class of the frequency distribution.
weight
(lbs.)
frequency
0.0 - 0.9
6
1.0 - 1.9
11
2.0 - 2.9
4
3.0 - 3.9
7
4.0 - 4.9
18
4/21
4/46
21/46
21/21

Explanation:

Step1: Calculate total frequency

Sum all frequencies: \(6 + 11+4 + 7+18=46\)

Step2: Calculate relative frequency

Relative frequency formula: \(\text{Relative Frequency}=\frac{\text{Frequency of class}}{\text{Total Frequency}}\). For the third class (frequency = 4), \(\text{Relative Frequency}=\frac{4}{46}\)

Answer:

\(\frac{4}{46}\) (Second option in the given choices)
