Question 2

Inc. Technology reported the results of consumer survey in which 300 Internet users indicated their level of agreement with the following statement: "The government needs to be able to scan Internet messages and user communications to prevent fraud and other crimes."  The possible responses were "agree strongly", "agree somewhat", "disagree somewhat", and "disagree strongly".  The number of Internet users in each category is summarized in the table.



In order to determine whether the true proportions of Internet users in each response category differ, a one-way chi-square analysis should be conducted. Which of the following statements is not necessary for the analysis to be valid?
◦ The probabilities for the four response outcomes remain the same from one internet user to the next.
◦ The expected cell counts all must be 30 or more.
