random sample of 9600 students.
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 those with at least one parent who was college grad would be higher of lower than 46%. Explain

Thank you
