Step-by-step explanation:
Conditional relative frequency is a frequency that is obtained in fraction that tells you what particular group has a particular feature.
In the questions above
Total number of high school students = 347
We have 3 groups based on their political tendencies
Liberal
Total number of Liberal students: 95
Total number of male Liberal Students = 27
Total number of female Liberal student = 95 - 27 = 68
Moderate
Total number of moderate students: 128
Total number of female moderate Students = 91
Total number of male moderate students is calculated as = 128 - 91
= 37
Conservative
Total number of conservative students: is not given in the question.
This is calculated as Total number of High school student - ( Total number of Liberal students + Total number of Moderate students)
347- (95+128) = 347- 223
= 124
Total number of female conservative Students= 93
Total number of male conservative students was not given in the question. Therefore it is calculated as = 124 -93 = 31
To determine the conditional relative frequency of males = Total number of high school male students in the school ÷ Total number of high school students in the school
Total number of male high school students is calculated as = Number of male Liberal students + Number of male Moderate students + Number of male Conservative students.
= 27 + 37 + 31
= 95 male high school students.
Hence the Conditional relative frequency of males = 95/347
The conditional relative frequency of male is 0.274
How to determine the conditional relative frequency of male?
The given parameters are:
Sample size = 347
- Liberal students: 95
- Male Liberal Students = 27
- Moderate students: 128
- Female moderate Students = 91
- Female conservative Students= 93
The number of male students is calculated as:
Male = Male Liberal + Male Moderate + Male conservative
This gives
Male = Male Liberal + (Moderate - Female moderate) + (Conservative - Female conservative)
So, we have:
Male = 27 + (128 - 91) + (Conservative - 93)
Male = Conservative - 29
The number of conservative students is:
Conservative = Sample size - Liberal students - Moderate students
This gives
Conservative = 347- 95 - 128
Conservative = 124
Recall that:
Male = Conservative - 29
This gives
Male = 124 - 29
Evaluate the difference
Male = 95
The conditional relative frequency of male is then calculated as:
CF = Male/Sample size
CF = 95/347
CF = 0.274
Hence, the conditional relative frequency of male is 0.274
