I want to thank, first and foremost my supervisor, Miss Yusralina bt Yusof for providing me the opportunity to taking part in this Final Year Project. I am so grateful for her help, professionalism and valuable guidance throughout this project that I do not have enough words to give my sincere appreciation. I would also like to thank all the staffs that involve in the analysis of data for this research project. Without their passionate participation and input, the analysis of data could not have successfully conducted. I am indebted to my friends who support me in this research project through the entire year. I cannot find words to express my gratitude to them in making this research project to fruition. I consider it an honor to work with all of them during this project. Last but not least, I must express my profound gratitude to my parents for providing me with unfailing support throughout my years of study and through the process of researching and writing this thesis. This thesis would not have been possible without them. Thank you.
