Question

Dr. Mitchell owns a veterinarian clinic. For a week, he collected data during examinations on the kind of animal a boy or girl has as a pet. Based on the data collected, which statement is true?

Answer 1

Answer: A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.

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.
