The cumulative relative frequency of the number of refrigerators sold per day the Appliance store is

Number of units Cumulative relative frequency

0 0.2

1 0.4

2 0.5

3 0.75

4 1.00

What is the relative frequency of sales of 2 units per day?

Answer: 0.1

Step-by-step explanation:

We know that the to find the cumulative relative frequency we add all of the previous relative frequencies to the corresponding relative frequency.

Given Table:

Number of units (per day) Cumulative relative frequency

0 0.2

1 0.4

2 0.5

3 0.75

4 1.00

The Cumulative relative frequency corresponds to 2 units per day = 0.5

The Cumulative relative frequency corresponds to previous row (1 units per day) = 0.4

Now, the relative frequency of sales of 2 units per day = 0.5-0.4=0.1

Hence, the relative frequency of sales of 2 units per day = 0.1
