The Gallup Organization asked 1050 randomly selected adult Americans age 18 or older who consider themselves to be religious, "Do you believe it is morally acceptable or morally wrong [rotated] to conduct medical research using stem cells obtained from human embryos?" The same question was asked to 1050 randomly selected adult Americans age 18 or older who do not consider themselves to be religious. The goal of the study was to determine whether the proportion of religious adult Americans who believe it is morally wrong to conduct medical research using stem cells obtained from human embryos differed from the proportion of non-religious adult Americans who believe it is morally wrong to conduct medical research using stem cells obtained from human embryos.
Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitative.
