A political scientist wants to know how a random sample of 18- to 25-year-olds feel about Democrats and Republicans in Congress. She obtains a random sample of 1030 registered voters 18 to 25 years of age and asks, "Do you have favorable/ unfavorable [rotated] opinion of the Democratic/Republican [rotated] party?" Each individual was asked to disclose his or her opinion about each party.
Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitative.
