Question

Refer to the following distribution of ages: Ages Frequency 40 up to 50 10 50 up to 60 28 60 up to 70 12 For this distribution of ages, what is the relative class frequency for the lowest class?

Answer 1

Answer:

The relative class frequency for the lowest class is 0.2.

Step-by-step explanation:

The given frequency table is

Ages         Frequency

40-50             10

50-60            28

60-70             12

Total               50

It means sample size is 50.

Formula for relative frequency is

$\text{Relative frequency}=\dfrac{\text{Class frequency}}{\text{Sample size}}$

We need to find the relative class frequency for the lowest class.

So, relative class frequency for class interval 40-50.

$\text{Relative frequency}=\dfrac{10}{50}=0.2$

Therefore, the relative class frequency for the lowest class is 0.2.
