Question
The editor of a magazine knows that 40.1% of all people who subscribe to the magazine do not renew their subscriptions. In an attempt to decrease this percentage, current subscribers are offered a renewal offer - one that offers current subscribers to renew their subscription at a substantially reduced price. After a period of six-months, the magazine editor wishes to investigate if this renewal offer does decrease the percentage of subscribers who do not renew subscriptions, or p.
