1. During the Swine Flu pandemic, a study found that if someone in your family contracted
the Swine Flu, you had 1 in 8 chance of also contracting the disease. A random sample

a. Calculate a 90% confidence interval for the proportion of people who contract
Swine Flu after a family member does.
b. Is there statistical evidence that the proportion of family members who contract
the flu is different from the 1 in 8 chance as stated in the study?
