Respuesta :

Answer:       A                 B

Group 1     0.25          0.75

Group 2    0.44          0.56

Step-by-step 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

[tex]15+45=60[/tex]

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

[tex]\frac{15}{60}=0.25[/tex]

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

[tex]\frac{45}{60}=0.75[/tex]

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

[tex]20+25=45[/tex]

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

[tex]\frac{20}{45}=0.44[/tex]

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

[tex]\frac{25}{45}=0.56[/tex]

Hence,        A                 B

Group 1     0.25          0.75

Group 2    0.44          0.56

Answer:

Answer:       A                 B

Group 1     0.25          0.75

Group 2    0.44          0.56

Step-by-step 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
