Question

What are the relative frequencies, to the nearest hundredth, of the rows of the two way table?

Answer 1

Answer: A B

Group A 0.25 0.75

Group B 0.45 0.55

Explanation:

Since we have given that

Number of people of A in Group A = 15

Number of people of B in Group A = 45

Number of people of A in Group B = 20

Number of people of B in Group B = 25

Total number of people in Group A = 15+45 = 60

Total number of people in Group B = 20+25 = 45

So, Relative frequencies will be given below:

Relative frequency of A in Group A is given by

`(15)/(60)=0.25`

Relative frequency of B in Group A is given by

`(45)/(60)=0.75`

Relative frequency of A in Group B is given by

`(20)/(45)=0.45`

Relative frequency of B in Group B is given by

`(25)/(45)=0.55`

Hence, A B

Group A 0.25 0.75

Group B 0.45 0.55
