    Before you begin any analysis you must take a random sample of 200customers from the 335 provided in the file Market.xls.Use the Random Sample Generator, imbedded in this file, to do this.  Your answers to the assignment tasks below are to be based on your sample of 200 customers. Make sure you keep a safe copy of your sample, since you cannot use Random Sample Generator to reproduce the first sample, and we will use it again in the major assignment.
     
    To prepare your data file ready for analysis, you must take the following steps:
     
    1. Use the file Sample Generator in the data file Market.xlsto generate a random sample of 200 customers from the file.
    2. Copy your sample file to another spreadsheet for working on your assignment and save it with another file name. Remember to save another copy of your sample under a different name as a backup.
