2 The editor of a magazine wishes to obtain the views of a random sample of readers about the future of the magazine.
  1. A sub-editor proposes that they include in one issue of the magazine a questionnaire for readers to complete and return. Give two reasons why the readers who return the questionnaire would not form a random sample. The editor decides to use a table of random numbers to select a random sample of 50 readers from the 7302 regular readers. These regular readers are numbered from 1 to 7302 . The first few random numbers which the editor obtains from the table are as follows. $$49757 \quad 80239 \quad 52038 \quad 60882$$
  2. Use these random numbers to select the first three members in the sample.
