Frequency of people who like HAMSTERS = 20

Frequency of people who like OTHERS = 25

Step-by-step explanation:

(As the dual bar chart is not given in the question, it is incomplete. The dual bar chart of this question is attached below)

No. of people who like CAT = 40

From the chart, we can see that the number of men and number of women who like CAT are equal.

Which means that out of 40 people, 20 men like CAT and 20 women like CAT.

Considering that 20 men like CAT, the bar chart of men who like CAT has a frequency 20. If we see the chart of men who like CAT, it takes 4 vertical steps to get to the frequency of 20, which means that 1 step represents 20/4= 5.

One vertical step has a frequency of 5

One vertical step has means a frequency of 5

Men who like DOGS = 5 steps = 5(5) = 25 Men

Women who like DOGS = 6 steps = 6(5) = 30 Women

Total people who like DOGS = 25 Men + 30 Women = 55 people

One vertical step has means a frequency of 5

Men who like HAMSTER = 3 steps = 3(5) = 15 Men

Women who like HAMSTER = 1 steps = 1(5) = 5 Women

Total people who like HAMSTER = 15 Men + 5 Women = 20 people

One vertical step has means a frequency of 5

Men who like OTHERS = 2 steps = 2(5) = 10 Men

Women who like OTHERS = 3 steps = 3(5) = 15 Women

Total people who like OTHERS = 10 Men + 15 Women = 25 people

mean, 40.6
