    4-7 Question Two
    4.
    (Points: 8)
    Jim Royale has been working for the past twelve months as a trading standards officer in his local authority. His appointment was made after a long period of unemployment. His primary role is to listen to queries from unhappy consumers and deal with each of the complaints appropriately.

    Jim is due for his annual appraisal and feels that he is in a position where he can justify his improvement in efficiency in dealing with queries since he started the job. Jim, having gained a knowledge for bureaucracy whilst out of work had the foresight to record the number of queries he dealt with on a daily basis during his first eight weeks of work after an initial two weeks training period.

    He also recorded the number of queries dealt with during last eight-week period leading up to his appraisal.

    Jim asked a colleague to enter all the data he collected into SPSS and produce some basic descriptive statistics for him. The output obtained from the SPSS session is given in Appendix 2. Using the SPSS output, obtain for the two data sets:

    EARLYON -
    1) The mean (correct to 2 decimal places)
    2) The standard deviation (correct to 2 decimal places)

    LATERON -
    3) The mean (correct to 2 decimal places)
    4) The standard deviation (correct to 2 decimal places)

    Using the answers that you previously provided, calculate the coefficient of variation for the two different distributions and express your answers as percentages correct to one decimal place.

    1) 1st eight weeks (EARLYON) (% to one decimal place)
    2) final eight weeks (LATERON) (% to one decimal place)
