This one is a bit hard. I attempted it and asked my teacher about it and she only gave equations to do it and I tried it but the answer was still not correct. Could you please attempt it to so I can see where I went wrong. Thank you!

a) The Canadian government is considering a policy that would raise the legal alcohol and tobacco purchase age from 19 to 21. A random sample of Canadians from 3 different age groups was selected and asked whether they support the raising of legal alcohol and tobacco purchase age. Does a statistically significant relationship exist between age group and support for this policy? Use the five-step model and an alpha level of 0.001. Make sure that you interpret the results in terms of the original research question.
