When members of a philanthropic organization send out a fundraising letter, they get a return from about 6% of the people on their mailing list. They simulated 1000 mailings for samples of size n with success rate p = 0.06. The sample statistics from each simulation are shown in the table. Complete parts mean standard dev. 20 0.0598 0.0526 a) through c). 50 0.0601 0.0335 100 0.0601 0.0236 200 0.0602 0.0167 theoretical mean theoretical standard dev. 20 0.06 50 0.06 100 0.06 200 0.06 (Round to four decimal places as needed.) b) How close are the theoretical values to those that were observed?
