Step-by-step explanation:
Given that 40 people liked cats, that is 20 women and 20 men
Then the dual bar representing 20 is made up of 4 frequency bars
Then each frequency bar represents 20 ÷ 4 = 5 people
Thus
dogs = 25 (men) + 30 (women) = 55
hamster = 15 ( men) + 5(women) = 20
other = 10(men) + 15(women) = 25
Favourite pet frequency table
favourite pet frequency
cat 40
dog 55
hamster 20
other 25
A total of 40 + 55 + 20 + 25 = 140
