First usa, a major credit card company, is planning a new offer for their current cardholders. the offer will give double airline miles on purchases for the next 6 months if the cardholder goes online and registers for the offer. to test the effectiveness of the campaign, first usa recently sent out offers to a random sample of 50,000 cardholders. of those, 1184 registered. give a 95% confidence interval for the true proportion of those cardholders who will register for the offer. if the acceptance rate is only 2% or less, the campaign won’t be worth the expense. given the confidence interval you found, what would you say?
