Question: Tattoos (4.1) One of the first decisions the class had to make was what kind of sampling method to use.

(a) They knew that a simple random sample was the "preferred" method. With 1100 teachers in 40 different sessions, the class decided not to use an SRS. Give at least two reasons why you think they made this decision.

(b) The AP® Statistics class believed that there might be systematic differences in the proportions of teachers who had tattoos based on the subject areas that they taught. What sampling method would you recommend to account for this possibility? Explain a statistical advantage of this method over an SRS.
