Question:

Regular surveys are taken of India to find out about the state of their health and wellbeing.
A random sample of 2500 young adults from the age group 15–24 years gave the following results
for obesity.
Obese Not-Obese Total
Male 222 983 1205
Female 285 1010 1295
Total 507 1993 2500

A newspaper uses the survey results in an article with the following introduction.
Kiwi Girls More Obese than Boys.
A recent survey of young adults aged 15 – 24 years shows that females are more than 20% more likely to be obese than their male counterparts.

Do you agree with the article’s introduction?
Use the data from Table 1 to support your answer, showing full calculations.

Answer:

This is a relative risk problem. So I calculated the relative risk, which is 1.1946.

I have a problem with this, How do I calculate the percentage of this?

In the question, it says that 20% more likely, and in the answer sheet it says that " As this is not over 20% more, the article is not correct"
Because it is 19%.

So my problem is how to get 19% from 1.1946?

Thanks.
