Question

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

Answer 1

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=$\frac{18}{32}=0.4375\approx0.44$
