What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table? group 1: a 15 b 45 group 2: a 20 b 25

Step-by-step explanation:

Since we have given that

Group 1 : A = 15

B = 45

Group 2 : A = 20

B = 25

So, Two way table will be

                        A              B            Total

Group 1            15             45             60

Group 2           20            25             45

Total                 35            70            105

Relative frequency for A in Group 1 is given by                        

Relative frequency for B in Group 1 is given by    

Relative frequency for A in Group 2 is given by  

Relative frequency for B in Group 2 is given by  

So, The Relative frequencies will be

                        A              B            Total

Group 1            0.14         0.42          0.57

Group 2           0.19          0.23          0.42

Total                0.33         0.66            1
