Question

given the frequency table below, what is the relative frequency of the data value 7?
value frequency
4 8
5 5
6 8
7 9

Explanation:

Step1: Calculate total frequency

Sum the frequencies: \(8 + 5 + 8 + 9\)
\(= 13 + 8 + 9\)
\(= 21 + 9\)
\(= 30\)

Step2: Find relative frequency of 7

Relative frequency = Frequency of 7 / Total frequency
\(= \frac{9}{30}\)
Simplify: \(= 0.3\)

Answer:

\(0.3\)
