The frame for an education survey of students includes A = 2,000 high schools with 2,000,000 students. An epsem sample of n = 3,000 students is selected in two stages, a = 100 schools selected randomly and b = 30 students selected randomly in each selected school. of the selected students, 30% reported having access to computers at home. A published estimate gives the standard error of this percentage as 1.4%. Ignoring finite population corrections, and approximating (n − 1) by n, estimate the following: a) The design effect d² for the sample percentage. b) The within school intraclass correlation roh for percentage of students who have access to a computer at home.
