3. A certain community college sent out surveys to all 70 companies in the area that had hired 2009 graduates of the college. Only 9 of the companies who received a survey completed the questions and returned the survey to the college. Based on this fact, identify ALL the misuses of statistics in the following statement:

98% of companies responding to the latest survey indicate that they are very satisfied with recently hired employees who are 2009 graduates of our community college."
