A study showed that 65% of supermarket shoppers believe supermarket brands to be as good as national name brands. To investigate whether this result applies to its own product, the manufacturer of a national name-brand ketchup asked a sample of shoppers whether they believed that supermarket ketchup was as good as the national brand ketchup. If a sample of 100 shoppers showed 55 stating that the supermarket brand was as good as the national brand, what is the p-value?
