Refer to the following distribution of commissions: Monthly Commissions Class Frequencies $600 up to $800 3 $800 up to $1,000 7 $1,000 up to $1,200 11 $1,200 up to $1,400 22 $1,400 up to $1,600 40 $1,600 up to $1,800 24 $1,800 up to $2,000 9 $2,000 up to $2,200 4 What is the relative frequency for salespeople who earn from $1,600 up to $1,800?

Answer 1

Answer:

For this case the relative frequency is given by:

$Rel.freq = \frac{24}{120}=0.2$

Or 20 %

Step-by-step explanation:

We can answer the question creating the following table:

   Class             Frequency      Rel. Frequency

$600-$800             3                  3/120=0.025

$800-$1000            7                  7/120=0.059

$1000-$1200          11                  11/120=0.092

$1200-$1400          22                22/120=0.183

$1400-$1600          40                40/120=0.333

$1600-$1800          24                24/120=0.2

$1800-$2000         9                  9/120=0.075

$2000-$2200        4                  4/120=0.033

Total                       120                      1

What is the relative frequency for salespeople who earn from $1,600 up to $1,800?

For this case the relative frequency is given by:

$Rel.freq = \frac{24}{120}=0.2$

Or 20 %

Answer 2

Relative frequency is also referred to as the empirical probability, which is calculated by the division of each frequency by the total number of frequency in the sample.

Find the table in the given attachment below.

To calculate the relative frequency of the salesperson earning from $1600 to $1800 is:

Relative frequency = $\dfrac{24}{120} = 0.2$

Thus, the relative frequency of the salespeople is 0.2 or 20%.
