Telephone interviews were conducted on a representative sample of 1,003 adults living in the United States. For this sample, 248 adults stated that they do not use the Internet, 249 revealed that they use the Internet but have never paid to download music, and the remainder (506 adults) admitted that they use the Internet and have paid to download music. The results are summarized in the Minitab pie chart shown.
