This is your proposal and its feedback from my tutor. Then I going to let you do the dissertation.Which you need to make up (fake) a statistics.From your proposal states that we need to survey 250 students but now my tutor allows me to make a survey just 50 London students only.
So, I need you to do this dissertation like you finished a survey.Also you need to tell me how much a statistics you need me to fill in a survey 50 papers questionnaire. (This is importance I have to report all number result of survey to my tutor).
