A recent report concludes that while Internet users like the convenience of online shopping, they do have concerns about privacy and security (Online Shopping, Washington, DC Pew Internet & American Life Project FEBRUARY 2008). A random sample of adults were asked to indicate their level of agreement with the statement €œI don€™t like giving my credit card number or personal information online.€ The table gives a subset of responses. Test an appropriate hypothesis for the relationship between age and level of concern about privacy and security online.

a) Select the appropriate procedure.
b) Check the assumptions.
c) State the hypotheses.
d) Test an appropriate hypothesis and state your results.
e) Interpret the meaning of the results and state a conclusion.
