  1. Betty is a common diminutive of the name Elizabeth. As a result, many people think Betty White’s real first name is Elizabeth – but how large a proportion? Betty took a random sample of 265 people and found that 147 of them believe that Betty White’s real first name is Elizabeth. At the .05 level of significance, is there evidence that a majority (more than 50%) of all people think Betty White’s real first name is Elizabeth?
