A research company was hired to collect data on the yearly advertising expenditure ($000's) for a random sample of fast food chains taken from 3 Caribbean countries; Trinidad and Tobago, Jamaica and Barbados.
A random sample of properties was hence taken from each of these countries. The data collected was
entered on a Minitab spreadsheet for analysis. Exhibit I below was subsequently generated.
