Cell phones. Many people have trouble setting up all the features of their cell phones, so a company has developed what it hopes will be easier instructions. The goal is to have at least 96% of customers succeed. The company tests the new system on 200 people, of whom 188 were successful. Is this strong evidence that the new system fails to meet the company’s goal? A student’s test of this hypothesis is shown. How many mistakes can you find?

There is strong evidence the new instructions don’t work.
