Answer the following questions about the information in your contingency table:

1. If a person is randomly selected from the survey participants, what is the probability that the person will be left-handed? 5/30 or 1/6or0.166
2. If you randomly choose a female from the people you surveyed, what is the probability that she is left-handed? 2/15 or0.133
3. What is the odds ratio of choosing a left-handedfemale? 2/13 divided by 3/12 =0.615OR(2*12)/(3*13) =0.615
4. What is the relative risk of choosing a left-handedfemale? 2/5 divided by 13/25= 10/13 or0.769

1. How do the probabilities and percentages for your study compare to those in the study you read?

According to Orr's article (2001), left-handed people make up around 10% of the overall population.That translates to 1 out of 10 people surveyed are left-handed.I gathered from my survey that 17% or 0.17 were left-handed.So,1 out of 6 people.My results were slightly higher in left-handed people.Ihave what is considered anEmpirical (or Statistical) probability since I surveyed people and included data via a table.
