Question
A philanthropic organization sent free mailing labels and greeting cards to a random sample of 100,000 potential donors on their mailing list and received 4821 donations. They have had a contribution rate of 5% in past campaigns, but a staff member worries that the rate will be lower if they run this campaign as currently designed. Complete parts 1 through 3 below. Assume the independence assumption is met.
1) What are the hypotheses?
Which hypotheses below will test the staff member's
worries?
2) Are the assumptions and conditions for inference met?
Which assumptions and conditions below are met? Select all that apply.
3) Do you think the donation rate would
drop?
5%.
