Answer:A)The conditional relative frequency among widowed employees of those widowed working at grade 2 or below= 28/42 = 66.67%
Step-by-step explanation:
In a two way frequency table, conditional relative frequency is it’s a fraction that tells us how many elements of of a group have a certain characteristic.
Here In a study about the relationship between marital status and job level, 8,235 males at a large manufacturing firm reported their job grade (from 1 to 4, with 4 being the highest) and their marital status.
from the given two way frequency table,
Number of widowed employees at grade 1 =8
Number of widowed employees at grade 2=20
∴ Number of widowed employees at grade 2 or below=8+20=28
And the total widowed employees working =42
Now the conditional relative frequency among widowed employees of those widowed working at grade 2 or below=
Therefore, the conditional relative frequency among widowed employees of those widowed working at grade 2 or below= 28/42 = 66.67%
