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

           A         B

Group A        0.25      0.75

Group B        0.45      0.55

Step-by-step explanation:

Since we have given that

Number of people of A in Group A = 15

Number of people of B in Group A = 45

Number of people of A in Group B = 20

Number of people of B in Group B = 25

Total number of people in Group A = 15+45 = 60

Total number of people in Group B = 20+25 = 45

So, Relative frequencies will be given  below:

Relative frequency of A in Group A is given by

Relative frequency of B in Group A is given by

Relative frequency of A in Group B is given by

Relative frequency of B in Group B is given by

Hence,             A         B

Group A        0.25      0.75

Group B        0.45      0.55

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
