Answer: The relative frequency of column A in group 1=[tex]0.75[/tex]
The relative frequency of column B in group 1=[tex]0.25[/tex]
The relative frequency of column A in group 2=[tex]0.56[/tex]
The relative frequency of column B in group 2=[tex]0.44[/tex]
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=[tex]\frac{102}{136}=0.75[/tex]
The relative frequency of column B in group 1=[tex]\frac{34}{136}=0.25[/tex]
For group 2 : Total =18+14=32
The relative frequency of column A in group 2=[tex]\frac{18}{32}=0.5625\approx0.56[/tex]
The relative frequency of column B in group 2=[tex]\frac{18}{32}=0.4375\approx0.44[/tex]
