This assignment must be typed, word-processed or clearly hand-written (but plots and graphs must be done using EXCEL or equivalent software), and submitted online as a single file through Moodle. Important note: The file size must not be over 50MB. • It is expected that Excel would be used to assist in statistical calculations for questions in this assignment. Where Excel is used, use copy function, "Snipping tool" or similar to cut and paste relevant parts of the spreadsheet to verify that you have done the work. • For those questions where Excel is not used to do the computations, all formulae and working must be included to obtain full marks. • Only one file will be accepted in any of the formats mentioned above. No zipped file or any other file extension will be accepted. Assignment markers will be looking for answers which • demonstrate the student's ability to interpret and apply the statistical techniques in the scenarios and • use statistical techniques as decision making tools in the business environment. Full marks will not be awarded to answers which simply demonstrate statistical procedures without comment, interpretation or discussion (as directed in the questions). the questions will be attached in the below file,check it.
