You would subtract.

The question is asking who has more, so to find out, you need to take away the smaller amount from the bigger amount. (1.25-1.05)

What are the related frequencies to the nearest hundredth of the columns of the two way table?
Eddi Din [679]

Answer: The relative frequency of column A in group 1=0.75

The relative frequency of column B in group 1=0.25

The relative frequency of column A in group 2=0.56

The relative frequency of column B in group 2=0.44

Step-by-step explanation:

The relative frequency is the ration of each frequency by the total value in particular group.

For group 1 : Total =102+34=136

The relative frequency of column A in group 1=\frac{102}{136}=0.75

The relative frequency of column B in group 1=\frac{34}{136}=0.25

For group 2 : Total =18+14=32

The relative frequency of column A in group 2=\frac{18}{32}=0.5625\approx0.56

The relative frequency of column B in group 2=\frac{18}{32}=0.4375\approx0.44
