random sample of 9600 students. Multistage design effect similar to an SRS (for those still in school)
46% had at least one parent who was a college graduate.
Estimate with 99% confidence the proportion of all students who had at least one parent who was a college grad.

b) Sample does not include drop outs so estimate is valid only for students.
Do you think proportion of ALL students with at least one parent who was college grad would be higher of lower than 46%. Explain. Thank you.
