Question

step 1 of 2: determine the relative frequency for the third class as a simplified fraction.

cost of a paperback book (in dollars)
class | frequency
5.8–6.7 | 9
6.8–7.7 | 11
7.8–8.7 | 15
8.8–9.7 | 10
9.8–10.7 | 9

Explanation:

Step1: Calculate total frequency

$9 + 11 + 15 + 10 + 9 = 54$

Step2: Identify third class frequency

Third class frequency = 15

Step3: Compute relative frequency

$\text{Relative Frequency} = \frac{15}{54} = \frac{5}{18}$

Answer:

$\frac{5}{18}$
