When members of a philanthropic organization send out a fundraising letter, they get a return from about 7% of the people on their mailing list. They simulated 1000 mailings for samples of size n with success rate p = 0.07. The sample statistics from each simulation are shown in the table. Complete parts mean standard dev.
