Answer 1

I'll prefer to answer from the last part

c) Clearly the population under study is consist of all American adults because the survey is making an inference about all the American adults.

b)The sample is given to be of size 1000 American adults which are randomly selected from all American adults

a) Variable for the study must be qualitative in nature because the variable ask whether adults approve or disapprove the way Congress works and the answer for the same is either YES or NO.
