Question

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table?

Group 1: 15 45

Group 2: 20 25


Drag and drop the values into the boxes to show the relative frequencies.

Answer 1

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 2

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
