Geogrge and Jerry are working on their final project for AP Statistics. They wish to investigate the question, "Do people really read documents they are asked to sign?" They believe that fewer than half of all people read a document they have been asked to sign. To test their theory, they randomly select 50 individuals rom various locations and then present them with various fake documents. After being presented with the documents, the individul are asked to sign them. George and Jerry then observe whether or not the individuals read the document. Out of the 50 individuals they select, 7 read tthe document, but then refuse to sign it anyway; 15 read it and sign, and the remaining 28 do not read but sign anyway. Does the sample result provide sufficient evidence to support George and Jerryy's theory that fewer than half of all people actually read a document they have been asked to sign?
