A study published in the journal Environmental Health found that flight attendants get cancer more often than the general population. The 5,3665{,}3665,3665, comma, 366 flight attendants in the study had higher incidence rates for every type of cancer examined, even though they had relatively lower rates of smoking and obesity. What type of study is this, and what is the response variable? Choose 1 answer: Choose 1 answer: (Choice A) A An observational study where the incidence rate of cancer is the response variable (Choice B, Checked) B An observational study where type of person (flight attendant or not) is the response variable (Choice C) C An experiment where where incidence rate of cancer is the response variable (Choice D) D An experiment where type of person (flight attendant or not) is the response variable

As per the above study published in the journal of environmental health the flight attendants get cancer more than the general population. Where the 366 flight attendants have higher rates of cancer.

Even though the flight attendants have a relatively lower level of obesity and smoking rate they still had higher cancer rates.
