Answer: A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
Step-by-step explanation:
Here are the options:
A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
B) A boy is 33% more likely than a girl to own a dog than a cat or other animal.
C) A boy is 50% more likely than a girl to own a dog than a cat or other animal.
D) A boy is 52% more likely than a girl to own a dog than a cat or other animal.
Boy with a dog = 27
Total animals owned by boys = 27+15+10 = 52
Probability of owning a dog = 27/52 = 0.5192
Girl with dogs = 18
Total animals owned by girls = 18+25+12 = 55
Probability of owning a dog = 18/55 = 0.3273
Therefore, 0.5192 - 0.3273 = 0.1919 = 19.19%
Therefore, A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
