Answer:

Answer: A B

Group 1 0.25 0.75

Group 2 0.44 0.56

Explanation:

Since we have given that

Number of people of A in group 1 = 15

Number of people of B in group 1 = 45

Total number of people in group 1 is given by

Relative frequency of people of A in Group 1 is given by

Relative frequency of people of B in Group 1 is given by

Similarly, Number of people of A in group 2 = 20

Number of people of B in group 2 = 25

Total number of people in group 2 is given by

Relative frequency of people of A in Group 2 is given by

Relative frequency of people of B in Group 2 is given by

Hence, A B

Group 1 0.25 0.75

Group 2 0.44 0.56

Answer: A B

Group 1 0.25 0.75

Group 2 0.44 0.56

Explanation:

Since we have given that

Number of people of A in group 1 = 15

Number of people of B in group 1 = 45

Total number of people in group 1 is given by


15+45=60

Relative frequency of people of A in Group 1 is given by


(15)/(60)=0.25

Relative frequency of people of B in Group 1 is given by


(45)/(60)=0.75

Similarly, Number of people of A in group 2 = 20

Number of people of B in group 2 = 25

Total number of people in group 2 is given by


20+25=45

Relative frequency of people of A in Group 2 is given by


(20)/(45)=0.44

Relative frequency of people of B in Group 2 is given by


(25)/(45)=0.56

Hence, A B

Group 1 0.25 0.75

Group 2 0.44 0.56
