Question

question
the cumulative relative frequency table for a set of data is shown below.
what is the missing cumulative relative frequency?

data	frequency	relative frequency	cumulative relative frequency
3	2	0.2	0.3
5	1	0.1	0.4
7	4	0.4	\\(\square\\)
8	2	0.2	1.0

provide your answer below:

Explanation:

Step1: Recall cumulative relative frequency

Cumulative relative frequency is the sum of the relative frequencies up to the current data point.

Step2: Add previous cumulative and current relative

The previous cumulative relative frequency (for data 5) is 0.4, and the relative frequency for data 7 is 0.4. So we calculate \( 0.4 + 0.4 \).
\( 0.4 + 0.4 = 0.8 \)

Answer:

0.8
