Hi could i get some help with this please? thank you!

Apply an appropriate test of hypotheses to determine if the Singaporeans were less satisfied with life in 2012 than they were in 2002. include the following:

(a) State the null and alternative hypotheses and explain how you develop these two hypotheses.

(b) Execute the five-steps procedure for the hypothesis testing with =0.01. Report the relevant statistics you have used for this test.

(c) Discuss the assumptions you have made in performing the test. Are these assumptions reasonable? provide explanations.
