A large manufacturer that sells consumer products on-line wishes to publicize its customer satisfaction in an advertisement. Specifically, it wants to state that over 90% of the manufacturer's customers would tell a friend to buy a product from the manufacturer. The manufacturer selects a random sample of 400 customers from its database, contacts them via email and asks them the question "Would you tell a friend to buy a product from us?" 372 say Yes, and 28 say No. Is thos enough evidence for this manufacturer to state that more than 90% of its costumers would tell their friend to buy a product from the manufacturer?
