In its Millennium Development Goals Report, the United Nations suggested that by the end of 2013 there will be 6.8 billion cell-phone subscription plans, and approximately 2.7 billion people will be connected to the Internet. A random sample of households in Brazil and Russia was obtained, and the number of people connected to the Internet was recorded for each. The data are given in the following table.
