Question

What are the relative frequencies to the nearest hundredth of the columns of the two-way table?

Answer 1

A B

Group 1. 0.33 0.81

Group 2. 0.67 0.19

Explanation:

To answer this question we must add the frequencies of A and B

This is:

Group 1: f(A) = 24

Group 2: f(A) = 48

Total (A) = 24 + 48 = 72

Then

Group 1: f(B) = 44

Group 2: f(B) = 10

Total (B) = 44 +10 = 54

Now we divide each value of f(A) between the total of (A) and each value of f(B) between the total of (B)

A B

Group 1.
`(24)/(72) = 0.33`
`(44)/(54) =0.81`

Group 2.
`(48)/(72)=0.67`
`(10)/(54)=0.19`
