Abank wants to get new customers for their credit card. they try two different approaches in their marketing campaign. the first promises a "cash back" reward; the second promises low interest rates. a sample of 500 people was mailed the first brochure; of these, 100 get the credit card. a separate sample of 500 people was mailed the second brochure; 125 get the credit card. are the two campaigns equally attractive to customers? find the test statistic. and compute a 95% confidence interval for the difference between the two proportions
