Question

Does a "follow-up reminder" increase the renewal rate on a magazine subscription? A magazine sent out 760 subscription renewal notices (without a reminder) and got 703 renewals. As an experiment, they sent out 240 subscription renewal notices (with a reminder) and got 228 renewals.
(a) At α = .05, was the renewal rate higher in the experimental group?
(b) Can normality be assumed?
