Are people moving away from having a traditional landline telephone in their homes? A recent report stated that 58% of U.S. households still have a landline telephone. Suppose a random sample of 200 homes was taken and a resident of the home was asked, "Do you have a traditional telephone in your place of residence?" Further suppose that of those asked, 120 said that they have a traditional telephone.
