Test whether people with a specific genetic marker are more likely to have suffered from clinical depression than people without the genetic marker, using the information that 40% of the 45 people in a sample with the genetic marker have had clinical depression while 12% of the 750 people in the sample without the genetic marker have had clinical depression. Use subscripts 1 for yes these people have the genetic marker and 2 for no these people do not have the genetic marker.
